Magnetic Sensor Selection

The following information is supplied for assistance in selecting the proper sensors for your

particular applications One of the fundamental questions to be answered is ldquoWill there be enough

sensor output voltage at the lowest operating speedrdquo

The sensor output voltage depends on

bull Surface Speed - speed target passes pole piece

bull Gap - distance between target and pole piece

bull Target Size - geometric relationship of pole piece and target

bull Load Impedance - connected to sensor

The surface speed of a gear depends upon its diameter and RPM Surface speed is expressed in

terms of inches per second (IPS)

Surface Speed (IPS) = RPM x Outside Dia (in) x π60

There is an optimum pitch (or tooth size) to

obtain the highest possible output from a sensor

but this is seldom necessary Figure 4 illustrates

the relationship of tooth size and spacing for

optimum magnetic sensor output Using a fine

tooth gear relative to a large pole piece diameter

sensor results in a lower generated voltage

because the flux also passes into adjacent teeth

resulting in a lower total flux variation

The relationship between pole piece diameter and

gear pitch and its effect on the output of a sensor

is described in Table A

Table A Relative Output Vs Gear Pitch

The load impedance with relation to the internal impedance of the sensor dictates the amount

of sensor output voltage that will be seen by that load Magnetic sensors are designed with the

lowest practical impedance consistent with providing maximum output The load impedance should

be high in relation to the impedance of the sensor to minimize the voltage drop across the coil and

to deliver the maximum output to the load

Most of the output voltages listed in this catalog are based on a load impedance of 100k ohms

To use a generality the load impedance should be 10 times that of the sensor

In order to assist you in selecting your sensor Al-Tek Instruments has developed an output vs

speed curve for each sensor family By looking at the application extremes of highest speedlowest

gap and lowest speedhighest gap the full variation of sensor output can easily be determined We

also specify each family in two ways Standard - minimum output voltage at 1000 IPS 0005 in

gap Guarantee Point - minimum output voltage at 500 IPS 0030 in gap Sensors with 187rdquo dia

pole piece are tested with an 8 DP gear 100k ohms load 106rdquo dia amp smaller pole piece sensors

are tested with a 20 DP gear 100k ohms load Sensors with connectors also use a 250 pf capaci-

tor shunted across the load

Calculation of Output Voltage

Selection of the proper Al-Tek magnetic sensor may require the calculation of sensor output volt-age to assure proper operation in your specific application To assist in this area let us consider thefollowing typical application Requirement is speed display with overspeed and underspeed control aswell as 4-20 mA signal to a PLC Speed range is 0-3600 RPM with low speed set point at 300 RPMavailable shaft diameter for mounting a gear is 2000 in and a 030 in air gap is ideal

You have selected a Tachtrol 30 PN T77630-10 with a 60T steel split gear PN G79870-202-1901 andyou are considering to use sensor PN 70085-1010-001 The question is if the sensor has enoughoutput voltage at 300 RPM

We can list the following parameters

a Tachtrol 30 Load impedance - 12k-ohmsSensitivity - 200 mV peak

b Split gear Outside dia - 5166 in DP - 12No of Teeth - 60

c SensorStandard output voltage - 40V (P-P) minGuarantee Point - 34V P-P minDC Resistance - 130 ohms maxTypical inductance - 33 mH ref

Step 1 Calculate surface speed of gearSS = RPM x Outside Dia x π = 300 x 5166 x 314 SS = 81 IPS

60 60

Step 2 Determine Peak-to-Peak output voltageReferring to the performance curves of sensor PN 70085-1010-001 the min output voltageis approx03 V (P-P) at 81 IPS and 0030 in gap It is a fact that output voltage vs surfacespeed is a near linear function therefore another method of determining output voltage isto set up a ratio using the guarantee point

34V (P-P) = E E = 55V (P-P)500 IPS 81

Step 3 Correction for pitchFor a 0106 in pole piece dia and a 12 DP gear the correction factor from Table A is 1 41(See pg 5)

Ec= 55 x 141 = 78 V (P-P)

Step 4 Converting to peak voltage Simply divide by 2 Ec = 78 divide 2 = 39V peak

Step 5 Correction for loadThe 39V or 390mV sensor output voltage will be divided across the impedance of the loadand sensor The load impedance is 12000 ohms resistive The impedance of the sensor hasa resistive and inductive element At low frequencies the inductive element is very small andcan therefore be disregarded leaving the max DC resistance of 130 ohms for consideration

The load correction factor (fL) can be expressed as(fL) = Z (load) = 12000 = 99

Z (load) + Z (sensor) 12130

Ec = 99 x 390 = 386 mV peak

The final adjusted value is 386 mV peak

As stated earlier the sensitivity or threshold of the Tachtrol 30 is 200mV peak at the stated conditions the selection of PN 70085-1010-001 is acceptable

By setting up ratios you can determine that the minimum sensed speed is 155 RPM

If the final value of Ec had been slightly less than 200 mV a reduction of the air gap (from 030rdquo

to 025rdquo) would boost the output above 200 mV

If it should be determined that the required sensor cannot be selected from the catalog modelsthe best procedure is to compile a list of all your requirements and contact your area distributor toassist you in the selection of the correct sensor

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Magnetic Sensor Selection

The following information is supplied for assistance in selecting the proper sensors for your

particular applications One of the fundamental questions to be answered is ldquoWill there be enough

sensor output voltage at the lowest operating speedrdquo

The sensor output voltage depends on

bull Surface Speed - speed target passes pole piece

bull Gap - distance between target and pole piece

bull Target Size - geometric relationship of pole piece and target

bull Load Impedance - connected to sensor

The surface speed of a gear depends upon its diameter and RPM Surface speed is expressed in

terms of inches per second (IPS)

Surface Speed (IPS) = RPM x Outside Dia (in) x π60

There is an optimum pitch (or tooth size) to

obtain the highest possible output from a sensor

but this is seldom necessary Figure 4 illustrates

the relationship of tooth size and spacing for

optimum magnetic sensor output Using a fine

tooth gear relative to a large pole piece diameter

sensor results in a lower generated voltage

because the flux also passes into adjacent teeth

resulting in a lower total flux variation

The relationship between pole piece diameter and

gear pitch and its effect on the output of a sensor

is described in Table A

Table A Relative Output Vs Gear Pitch

The load impedance with relation to the internal impedance of the sensor dictates the amount

of sensor output voltage that will be seen by that load Magnetic sensors are designed with the

lowest practical impedance consistent with providing maximum output The load impedance should

be high in relation to the impedance of the sensor to minimize the voltage drop across the coil and

to deliver the maximum output to the load

Most of the output voltages listed in this catalog are based on a load impedance of 100k ohms

To use a generality the load impedance should be 10 times that of the sensor

In order to assist you in selecting your sensor Al-Tek Instruments has developed an output vs

speed curve for each sensor family By looking at the application extremes of highest speedlowest

gap and lowest speedhighest gap the full variation of sensor output can easily be determined We

also specify each family in two ways Standard - minimum output voltage at 1000 IPS 0005 in

gap Guarantee Point - minimum output voltage at 500 IPS 0030 in gap Sensors with 187rdquo dia

pole piece are tested with an 8 DP gear 100k ohms load 106rdquo dia amp smaller pole piece sensors

are tested with a 20 DP gear 100k ohms load Sensors with connectors also use a 250 pf capaci-

tor shunted across the load

Calculation of Output Voltage

Selection of the proper Al-Tek magnetic sensor may require the calculation of sensor output volt-age to assure proper operation in your specific application To assist in this area let us consider thefollowing typical application Requirement is speed display with overspeed and underspeed control aswell as 4-20 mA signal to a PLC Speed range is 0-3600 RPM with low speed set point at 300 RPMavailable shaft diameter for mounting a gear is 2000 in and a 030 in air gap is ideal

You have selected a Tachtrol 30 PN T77630-10 with a 60T steel split gear PN G79870-202-1901 andyou are considering to use sensor PN 70085-1010-001 The question is if the sensor has enoughoutput voltage at 300 RPM

We can list the following parameters

a Tachtrol 30 Load impedance - 12k-ohmsSensitivity - 200 mV peak

b Split gear Outside dia - 5166 in DP - 12No of Teeth - 60

c SensorStandard output voltage - 40V (P-P) minGuarantee Point - 34V P-P minDC Resistance - 130 ohms maxTypical inductance - 33 mH ref

Step 1 Calculate surface speed of gearSS = RPM x Outside Dia x π = 300 x 5166 x 314 SS = 81 IPS

60 60

Step 2 Determine Peak-to-Peak output voltageReferring to the performance curves of sensor PN 70085-1010-001 the min output voltageis approx03 V (P-P) at 81 IPS and 0030 in gap It is a fact that output voltage vs surfacespeed is a near linear function therefore another method of determining output voltage isto set up a ratio using the guarantee point

34V (P-P) = E E = 55V (P-P)500 IPS 81

Step 3 Correction for pitchFor a 0106 in pole piece dia and a 12 DP gear the correction factor from Table A is 1 41(See pg 5)

Ec= 55 x 141 = 78 V (P-P)

Step 4 Converting to peak voltage Simply divide by 2 Ec = 78 divide 2 = 39V peak

Step 5 Correction for loadThe 39V or 390mV sensor output voltage will be divided across the impedance of the loadand sensor The load impedance is 12000 ohms resistive The impedance of the sensor hasa resistive and inductive element At low frequencies the inductive element is very small andcan therefore be disregarded leaving the max DC resistance of 130 ohms for consideration

The load correction factor (fL) can be expressed as(fL) = Z (load) = 12000 = 99

Z (load) + Z (sensor) 12130

Ec = 99 x 390 = 386 mV peak

The final adjusted value is 386 mV peak

As stated earlier the sensitivity or threshold of the Tachtrol 30 is 200mV peak at the stated conditions the selection of PN 70085-1010-001 is acceptable

By setting up ratios you can determine that the minimum sensed speed is 155 RPM

If the final value of Ec had been slightly less than 200 mV a reduction of the air gap (from 030rdquo

to 025rdquo) would boost the output above 200 mV

If it should be determined that the required sensor cannot be selected from the catalog modelsthe best procedure is to compile a list of all your requirements and contact your area distributor toassist you in the selection of the correct sensor

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Tachometer Transducers

when used with speed sensors They are designedprimarily to provide an easy means of attaching a pulsegenerating assembly to rotating shafts Sensor gap-ping shaft run-out and mounting problems are elimi-nated This makes the unit especially useful for shaftswith high run-out The ordering map on the followingpage provides information for selecting a unit for yourparticular application Please note that sensors andcable assemblies must be ordered separately

Taper-Lockreg Type

enables quick attachment to rotating shafts Thetransducer employs a rotor with small perforationsalong its periphery a permanently lubricated sealedbearing an outer ring and a reference rod whichwhen clamped in position prevents the outer ringassembly from moving The outer ring canaccomodate up to three speed sensors for use inmonitoring directions of rotation and speed

Sleeve Type

identical to the Taper-Lock type except that it providesa sleeve bushing with two set screws for installationpurposes allowing larger shaft sizes

It is the customers responsibility to determinewhether the product is proper for customers use andapplication

The assembly consists of a Taper-Lock bushing which

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Magnetic Sensor Selection

The following information is supplied for assistance in selecting the proper sensors for your

particular applications One of the fundamental questions to be answered is ldquoWill there be enough

sensor output voltage at the lowest operating speedrdquo

The sensor output voltage depends on

bull Surface Speed - speed target passes pole piece

bull Gap - distance between target and pole piece

bull Target Size - geometric relationship of pole piece and target

bull Load Impedance - connected to sensor

The surface speed of a gear depends upon its diameter and RPM Surface speed is expressed in

terms of inches per second (IPS)

Surface Speed (IPS) = RPM x Outside Dia (in) x π60

There is an optimum pitch (or tooth size) to

obtain the highest possible output from a sensor

but this is seldom necessary Figure 4 illustrates

the relationship of tooth size and spacing for

optimum magnetic sensor output Using a fine

tooth gear relative to a large pole piece diameter

sensor results in a lower generated voltage

because the flux also passes into adjacent teeth

resulting in a lower total flux variation

The relationship between pole piece diameter and

gear pitch and its effect on the output of a sensor

is described in Table A

Table A Relative Output Vs Gear Pitch

The load impedance with relation to the internal impedance of the sensor dictates the amount

of sensor output voltage that will be seen by that load Magnetic sensors are designed with the

lowest practical impedance consistent with providing maximum output The load impedance should

be high in relation to the impedance of the sensor to minimize the voltage drop across the coil and

to deliver the maximum output to the load

Most of the output voltages listed in this catalog are based on a load impedance of 100k ohms

To use a generality the load impedance should be 10 times that of the sensor

In order to assist you in selecting your sensor Al-Tek Instruments has developed an output vs

speed curve for each sensor family By looking at the application extremes of highest speedlowest

gap and lowest speedhighest gap the full variation of sensor output can easily be determined We

also specify each family in two ways Standard - minimum output voltage at 1000 IPS 0005 in

gap Guarantee Point - minimum output voltage at 500 IPS 0030 in gap Sensors with 187rdquo dia

pole piece are tested with an 8 DP gear 100k ohms load 106rdquo dia amp smaller pole piece sensors

are tested with a 20 DP gear 100k ohms load Sensors with connectors also use a 250 pf capaci-

tor shunted across the load

Calculation of Output Voltage

Selection of the proper Al-Tek magnetic sensor may require the calculation of sensor output volt-age to assure proper operation in your specific application To assist in this area let us consider thefollowing typical application Requirement is speed display with overspeed and underspeed control aswell as 4-20 mA signal to a PLC Speed range is 0-3600 RPM with low speed set point at 300 RPMavailable shaft diameter for mounting a gear is 2000 in and a 030 in air gap is ideal

You have selected a Tachtrol 30 PN T77630-10 with a 60T steel split gear PN G79870-202-1901 andyou are considering to use sensor PN 70085-1010-001 The question is if the sensor has enoughoutput voltage at 300 RPM

We can list the following parameters

a Tachtrol 30 Load impedance - 12k-ohmsSensitivity - 200 mV peak

b Split gear Outside dia - 5166 in DP - 12No of Teeth - 60

c SensorStandard output voltage - 40V (P-P) minGuarantee Point - 34V P-P minDC Resistance - 130 ohms maxTypical inductance - 33 mH ref

Step 1 Calculate surface speed of gearSS = RPM x Outside Dia x π = 300 x 5166 x 314 SS = 81 IPS

60 60

Step 2 Determine Peak-to-Peak output voltageReferring to the performance curves of sensor PN 70085-1010-001 the min output voltageis approx03 V (P-P) at 81 IPS and 0030 in gap It is a fact that output voltage vs surfacespeed is a near linear function therefore another method of determining output voltage isto set up a ratio using the guarantee point

34V (P-P) = E E = 55V (P-P)500 IPS 81

Step 3 Correction for pitchFor a 0106 in pole piece dia and a 12 DP gear the correction factor from Table A is 1 41(See pg 5)

Ec= 55 x 141 = 78 V (P-P)

Step 4 Converting to peak voltage Simply divide by 2 Ec = 78 divide 2 = 39V peak

Step 5 Correction for loadThe 39V or 390mV sensor output voltage will be divided across the impedance of the loadand sensor The load impedance is 12000 ohms resistive The impedance of the sensor hasa resistive and inductive element At low frequencies the inductive element is very small andcan therefore be disregarded leaving the max DC resistance of 130 ohms for consideration

The load correction factor (fL) can be expressed as(fL) = Z (load) = 12000 = 99

Z (load) + Z (sensor) 12130

Ec = 99 x 390 = 386 mV peak

The final adjusted value is 386 mV peak

As stated earlier the sensitivity or threshold of the Tachtrol 30 is 200mV peak at the stated conditions the selection of PN 70085-1010-001 is acceptable

By setting up ratios you can determine that the minimum sensed speed is 155 RPM

If the final value of Ec had been slightly less than 200 mV a reduction of the air gap (from 030rdquo

to 025rdquo) would boost the output above 200 mV

If it should be determined that the required sensor cannot be selected from the catalog modelsthe best procedure is to compile a list of all your requirements and contact your area distributor toassist you in the selection of the correct sensor

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Magnetic Sensor Selection

The following information is supplied for assistance in selecting the proper sensors for your

particular applications One of the fundamental questions to be answered is ldquoWill there be enough

sensor output voltage at the lowest operating speedrdquo

The sensor output voltage depends on

bull Surface Speed - speed target passes pole piece

bull Gap - distance between target and pole piece

bull Target Size - geometric relationship of pole piece and target

bull Load Impedance - connected to sensor

The surface speed of a gear depends upon its diameter and RPM Surface speed is expressed in

terms of inches per second (IPS)

Surface Speed (IPS) = RPM x Outside Dia (in) x π60

There is an optimum pitch (or tooth size) to

obtain the highest possible output from a sensor

but this is seldom necessary Figure 4 illustrates

the relationship of tooth size and spacing for

optimum magnetic sensor output Using a fine

tooth gear relative to a large pole piece diameter

sensor results in a lower generated voltage

because the flux also passes into adjacent teeth

resulting in a lower total flux variation

The relationship between pole piece diameter and

gear pitch and its effect on the output of a sensor

is described in Table A

Table A Relative Output Vs Gear Pitch

The load impedance with relation to the internal impedance of the sensor dictates the amount

of sensor output voltage that will be seen by that load Magnetic sensors are designed with the

lowest practical impedance consistent with providing maximum output The load impedance should

be high in relation to the impedance of the sensor to minimize the voltage drop across the coil and

to deliver the maximum output to the load

Most of the output voltages listed in this catalog are based on a load impedance of 100k ohms

To use a generality the load impedance should be 10 times that of the sensor

In order to assist you in selecting your sensor Al-Tek Instruments has developed an output vs

speed curve for each sensor family By looking at the application extremes of highest speedlowest

gap and lowest speedhighest gap the full variation of sensor output can easily be determined We

also specify each family in two ways Standard - minimum output voltage at 1000 IPS 0005 in

gap Guarantee Point - minimum output voltage at 500 IPS 0030 in gap Sensors with 187rdquo dia

pole piece are tested with an 8 DP gear 100k ohms load 106rdquo dia amp smaller pole piece sensors

are tested with a 20 DP gear 100k ohms load Sensors with connectors also use a 250 pf capaci-

tor shunted across the load

Calculation of Output Voltage

Selection of the proper Al-Tek magnetic sensor may require the calculation of sensor output volt-age to assure proper operation in your specific application To assist in this area let us consider thefollowing typical application Requirement is speed display with overspeed and underspeed control aswell as 4-20 mA signal to a PLC Speed range is 0-3600 RPM with low speed set point at 300 RPMavailable shaft diameter for mounting a gear is 2000 in and a 030 in air gap is ideal

You have selected a Tachtrol 30 PN T77630-10 with a 60T steel split gear PN G79870-202-1901 andyou are considering to use sensor PN 70085-1010-001 The question is if the sensor has enoughoutput voltage at 300 RPM

We can list the following parameters

a Tachtrol 30 Load impedance - 12k-ohmsSensitivity - 200 mV peak

b Split gear Outside dia - 5166 in DP - 12No of Teeth - 60

c SensorStandard output voltage - 40V (P-P) minGuarantee Point - 34V P-P minDC Resistance - 130 ohms maxTypical inductance - 33 mH ref

Step 1 Calculate surface speed of gearSS = RPM x Outside Dia x π = 300 x 5166 x 314 SS = 81 IPS

60 60

Step 2 Determine Peak-to-Peak output voltageReferring to the performance curves of sensor PN 70085-1010-001 the min output voltageis approx03 V (P-P) at 81 IPS and 0030 in gap It is a fact that output voltage vs surfacespeed is a near linear function therefore another method of determining output voltage isto set up a ratio using the guarantee point

34V (P-P) = E E = 55V (P-P)500 IPS 81

Step 3 Correction for pitchFor a 0106 in pole piece dia and a 12 DP gear the correction factor from Table A is 1 41(See pg 5)

Ec= 55 x 141 = 78 V (P-P)

Step 4 Converting to peak voltage Simply divide by 2 Ec = 78 divide 2 = 39V peak

Step 5 Correction for loadThe 39V or 390mV sensor output voltage will be divided across the impedance of the loadand sensor The load impedance is 12000 ohms resistive The impedance of the sensor hasa resistive and inductive element At low frequencies the inductive element is very small andcan therefore be disregarded leaving the max DC resistance of 130 ohms for consideration

The load correction factor (fL) can be expressed as(fL) = Z (load) = 12000 = 99

Z (load) + Z (sensor) 12130

Ec = 99 x 390 = 386 mV peak

The final adjusted value is 386 mV peak

As stated earlier the sensitivity or threshold of the Tachtrol 30 is 200mV peak at the stated conditions the selection of PN 70085-1010-001 is acceptable

By setting up ratios you can determine that the minimum sensed speed is 155 RPM

If the final value of Ec had been slightly less than 200 mV a reduction of the air gap (from 030rdquo

to 025rdquo) would boost the output above 200 mV

If it should be determined that the required sensor cannot be selected from the catalog modelsthe best procedure is to compile a list of all your requirements and contact your area distributor toassist you in the selection of the correct sensor

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Magnetic Sensor Selection

The following information is supplied for assistance in selecting the proper sensors for your

particular applications One of the fundamental questions to be answered is ldquoWill there be enough

sensor output voltage at the lowest operating speedrdquo

The sensor output voltage depends on

bull Surface Speed - speed target passes pole piece

bull Gap - distance between target and pole piece

bull Target Size - geometric relationship of pole piece and target

bull Load Impedance - connected to sensor

The surface speed of a gear depends upon its diameter and RPM Surface speed is expressed in

terms of inches per second (IPS)

Surface Speed (IPS) = RPM x Outside Dia (in) x π60

There is an optimum pitch (or tooth size) to

obtain the highest possible output from a sensor

but this is seldom necessary Figure 4 illustrates

the relationship of tooth size and spacing for

optimum magnetic sensor output Using a fine

tooth gear relative to a large pole piece diameter

sensor results in a lower generated voltage

because the flux also passes into adjacent teeth

resulting in a lower total flux variation

The relationship between pole piece diameter and

gear pitch and its effect on the output of a sensor

is described in Table A

Table A Relative Output Vs Gear Pitch

The load impedance with relation to the internal impedance of the sensor dictates the amount

of sensor output voltage that will be seen by that load Magnetic sensors are designed with the

lowest practical impedance consistent with providing maximum output The load impedance should

be high in relation to the impedance of the sensor to minimize the voltage drop across the coil and

to deliver the maximum output to the load

Most of the output voltages listed in this catalog are based on a load impedance of 100k ohms

To use a generality the load impedance should be 10 times that of the sensor

In order to assist you in selecting your sensor Al-Tek Instruments has developed an output vs

speed curve for each sensor family By looking at the application extremes of highest speedlowest

gap and lowest speedhighest gap the full variation of sensor output can easily be determined We

also specify each family in two ways Standard - minimum output voltage at 1000 IPS 0005 in

gap Guarantee Point - minimum output voltage at 500 IPS 0030 in gap Sensors with 187rdquo dia

pole piece are tested with an 8 DP gear 100k ohms load 106rdquo dia amp smaller pole piece sensors

are tested with a 20 DP gear 100k ohms load Sensors with connectors also use a 250 pf capaci-

tor shunted across the load

Calculation of Output Voltage

Selection of the proper Al-Tek magnetic sensor may require the calculation of sensor output volt-age to assure proper operation in your specific application To assist in this area let us consider thefollowing typical application Requirement is speed display with overspeed and underspeed control aswell as 4-20 mA signal to a PLC Speed range is 0-3600 RPM with low speed set point at 300 RPMavailable shaft diameter for mounting a gear is 2000 in and a 030 in air gap is ideal

You have selected a Tachtrol 30 PN T77630-10 with a 60T steel split gear PN G79870-202-1901 andyou are considering to use sensor PN 70085-1010-001 The question is if the sensor has enoughoutput voltage at 300 RPM

We can list the following parameters

a Tachtrol 30 Load impedance - 12k-ohmsSensitivity - 200 mV peak

b Split gear Outside dia - 5166 in DP - 12No of Teeth - 60

c SensorStandard output voltage - 40V (P-P) minGuarantee Point - 34V P-P minDC Resistance - 130 ohms maxTypical inductance - 33 mH ref

Step 1 Calculate surface speed of gearSS = RPM x Outside Dia x π = 300 x 5166 x 314 SS = 81 IPS

60 60

Step 2 Determine Peak-to-Peak output voltageReferring to the performance curves of sensor PN 70085-1010-001 the min output voltageis approx03 V (P-P) at 81 IPS and 0030 in gap It is a fact that output voltage vs surfacespeed is a near linear function therefore another method of determining output voltage isto set up a ratio using the guarantee point

34V (P-P) = E E = 55V (P-P)500 IPS 81

Step 3 Correction for pitchFor a 0106 in pole piece dia and a 12 DP gear the correction factor from Table A is 1 41(See pg 5)

Ec= 55 x 141 = 78 V (P-P)

Step 4 Converting to peak voltage Simply divide by 2 Ec = 78 divide 2 = 39V peak

Step 5 Correction for loadThe 39V or 390mV sensor output voltage will be divided across the impedance of the loadand sensor The load impedance is 12000 ohms resistive The impedance of the sensor hasa resistive and inductive element At low frequencies the inductive element is very small andcan therefore be disregarded leaving the max DC resistance of 130 ohms for consideration

The load correction factor (fL) can be expressed as(fL) = Z (load) = 12000 = 99

Z (load) + Z (sensor) 12130

Ec = 99 x 390 = 386 mV peak

The final adjusted value is 386 mV peak

As stated earlier the sensitivity or threshold of the Tachtrol 30 is 200mV peak at the stated conditions the selection of PN 70085-1010-001 is acceptable

By setting up ratios you can determine that the minimum sensed speed is 155 RPM

If the final value of Ec had been slightly less than 200 mV a reduction of the air gap (from 030rdquo

to 025rdquo) would boost the output above 200 mV

If it should be determined that the required sensor cannot be selected from the catalog modelsthe best procedure is to compile a list of all your requirements and contact your area distributor toassist you in the selection of the correct sensor

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Magnetic Sensor Selection

The following information is supplied for assistance in selecting the proper sensors for your

particular applications One of the fundamental questions to be answered is ldquoWill there be enough

sensor output voltage at the lowest operating speedrdquo

The sensor output voltage depends on

bull Surface Speed - speed target passes pole piece

bull Gap - distance between target and pole piece

bull Target Size - geometric relationship of pole piece and target

bull Load Impedance - connected to sensor

The surface speed of a gear depends upon its diameter and RPM Surface speed is expressed in

terms of inches per second (IPS)

Surface Speed (IPS) = RPM x Outside Dia (in) x π60

There is an optimum pitch (or tooth size) to

obtain the highest possible output from a sensor

but this is seldom necessary Figure 4 illustrates

the relationship of tooth size and spacing for

optimum magnetic sensor output Using a fine

tooth gear relative to a large pole piece diameter

sensor results in a lower generated voltage

because the flux also passes into adjacent teeth

resulting in a lower total flux variation

The relationship between pole piece diameter and

gear pitch and its effect on the output of a sensor

is described in Table A

Table A Relative Output Vs Gear Pitch

The load impedance with relation to the internal impedance of the sensor dictates the amount

of sensor output voltage that will be seen by that load Magnetic sensors are designed with the

lowest practical impedance consistent with providing maximum output The load impedance should

be high in relation to the impedance of the sensor to minimize the voltage drop across the coil and

to deliver the maximum output to the load

Most of the output voltages listed in this catalog are based on a load impedance of 100k ohms

To use a generality the load impedance should be 10 times that of the sensor

In order to assist you in selecting your sensor Al-Tek Instruments has developed an output vs

speed curve for each sensor family By looking at the application extremes of highest speedlowest

gap and lowest speedhighest gap the full variation of sensor output can easily be determined We

also specify each family in two ways Standard - minimum output voltage at 1000 IPS 0005 in

gap Guarantee Point - minimum output voltage at 500 IPS 0030 in gap Sensors with 187rdquo dia

pole piece are tested with an 8 DP gear 100k ohms load 106rdquo dia amp smaller pole piece sensors

are tested with a 20 DP gear 100k ohms load Sensors with connectors also use a 250 pf capaci-

tor shunted across the load

Calculation of Output Voltage

Selection of the proper Al-Tek magnetic sensor may require the calculation of sensor output volt-age to assure proper operation in your specific application To assist in this area let us consider thefollowing typical application Requirement is speed display with overspeed and underspeed control aswell as 4-20 mA signal to a PLC Speed range is 0-3600 RPM with low speed set point at 300 RPMavailable shaft diameter for mounting a gear is 2000 in and a 030 in air gap is ideal

You have selected a Tachtrol 30 PN T77630-10 with a 60T steel split gear PN G79870-202-1901 andyou are considering to use sensor PN 70085-1010-001 The question is if the sensor has enoughoutput voltage at 300 RPM

We can list the following parameters

a Tachtrol 30 Load impedance - 12k-ohmsSensitivity - 200 mV peak

b Split gear Outside dia - 5166 in DP - 12No of Teeth - 60

c SensorStandard output voltage - 40V (P-P) minGuarantee Point - 34V P-P minDC Resistance - 130 ohms maxTypical inductance - 33 mH ref

Step 1 Calculate surface speed of gearSS = RPM x Outside Dia x π = 300 x 5166 x 314 SS = 81 IPS

60 60

Step 2 Determine Peak-to-Peak output voltageReferring to the performance curves of sensor PN 70085-1010-001 the min output voltageis approx03 V (P-P) at 81 IPS and 0030 in gap It is a fact that output voltage vs surfacespeed is a near linear function therefore another method of determining output voltage isto set up a ratio using the guarantee point

34V (P-P) = E E = 55V (P-P)500 IPS 81

Step 3 Correction for pitchFor a 0106 in pole piece dia and a 12 DP gear the correction factor from Table A is 1 41(See pg 5)

Ec= 55 x 141 = 78 V (P-P)

Step 4 Converting to peak voltage Simply divide by 2 Ec = 78 divide 2 = 39V peak

Step 5 Correction for loadThe 39V or 390mV sensor output voltage will be divided across the impedance of the loadand sensor The load impedance is 12000 ohms resistive The impedance of the sensor hasa resistive and inductive element At low frequencies the inductive element is very small andcan therefore be disregarded leaving the max DC resistance of 130 ohms for consideration

The load correction factor (fL) can be expressed as(fL) = Z (load) = 12000 = 99

Z (load) + Z (sensor) 12130

Ec = 99 x 390 = 386 mV peak

The final adjusted value is 386 mV peak

As stated earlier the sensitivity or threshold of the Tachtrol 30 is 200mV peak at the stated conditions the selection of PN 70085-1010-001 is acceptable

By setting up ratios you can determine that the minimum sensed speed is 155 RPM

If the final value of Ec had been slightly less than 200 mV a reduction of the air gap (from 030rdquo

to 025rdquo) would boost the output above 200 mV

If it should be determined that the required sensor cannot be selected from the catalog modelsthe best procedure is to compile a list of all your requirements and contact your area distributor toassist you in the selection of the correct sensor

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Calculation of Output Voltage

Selection of the proper Al-Tek magnetic sensor may require the calculation of sensor output volt-age to assure proper operation in your specific application To assist in this area let us consider thefollowing typical application Requirement is speed display with overspeed and underspeed control aswell as 4-20 mA signal to a PLC Speed range is 0-3600 RPM with low speed set point at 300 RPMavailable shaft diameter for mounting a gear is 2000 in and a 030 in air gap is ideal

You have selected a Tachtrol 30 PN T77630-10 with a 60T steel split gear PN G79870-202-1901 andyou are considering to use sensor PN 70085-1010-001 The question is if the sensor has enoughoutput voltage at 300 RPM

We can list the following parameters

a Tachtrol 30 Load impedance - 12k-ohmsSensitivity - 200 mV peak

b Split gear Outside dia - 5166 in DP - 12No of Teeth - 60

c SensorStandard output voltage - 40V (P-P) minGuarantee Point - 34V P-P minDC Resistance - 130 ohms maxTypical inductance - 33 mH ref

Step 1 Calculate surface speed of gearSS = RPM x Outside Dia x π = 300 x 5166 x 314 SS = 81 IPS

60 60

Step 2 Determine Peak-to-Peak output voltageReferring to the performance curves of sensor PN 70085-1010-001 the min output voltageis approx03 V (P-P) at 81 IPS and 0030 in gap It is a fact that output voltage vs surfacespeed is a near linear function therefore another method of determining output voltage isto set up a ratio using the guarantee point

34V (P-P) = E E = 55V (P-P)500 IPS 81

Step 3 Correction for pitchFor a 0106 in pole piece dia and a 12 DP gear the correction factor from Table A is 1 41(See pg 5)

Ec= 55 x 141 = 78 V (P-P)

Step 4 Converting to peak voltage Simply divide by 2 Ec = 78 divide 2 = 39V peak

Step 5 Correction for loadThe 39V or 390mV sensor output voltage will be divided across the impedance of the loadand sensor The load impedance is 12000 ohms resistive The impedance of the sensor hasa resistive and inductive element At low frequencies the inductive element is very small andcan therefore be disregarded leaving the max DC resistance of 130 ohms for consideration

The load correction factor (fL) can be expressed as(fL) = Z (load) = 12000 = 99

Z (load) + Z (sensor) 12130

Ec = 99 x 390 = 386 mV peak

The final adjusted value is 386 mV peak

As stated earlier the sensitivity or threshold of the Tachtrol 30 is 200mV peak at the stated conditions the selection of PN 70085-1010-001 is acceptable

By setting up ratios you can determine that the minimum sensed speed is 155 RPM

If the final value of Ec had been slightly less than 200 mV a reduction of the air gap (from 030rdquo

to 025rdquo) would boost the output above 200 mV

If it should be determined that the required sensor cannot be selected from the catalog modelsthe best procedure is to compile a list of all your requirements and contact your area distributor toassist you in the selection of the correct sensor

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Tachometer Transducers

when used with speed sensors They are designedprimarily to provide an easy means of attaching a pulsegenerating assembly to rotating shafts Sensor gap-ping shaft run-out and mounting problems are elimi-nated This makes the unit especially useful for shaftswith high run-out The ordering map on the followingpage provides information for selecting a unit for yourparticular application Please note that sensors andcable assemblies must be ordered separately

Taper-Lockreg Type

enables quick attachment to rotating shafts Thetransducer employs a rotor with small perforationsalong its periphery a permanently lubricated sealedbearing an outer ring and a reference rod whichwhen clamped in position prevents the outer ringassembly from moving The outer ring canaccomodate up to three speed sensors for use inmonitoring directions of rotation and speed

Sleeve Type

identical to the Taper-Lock type except that it providesa sleeve bushing with two set screws for installationpurposes allowing larger shaft sizes

It is the customers responsibility to determinewhether the product is proper for customers use andapplication

The assembly consists of a Taper-Lock bushing which

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Tachometer Transducers

when used with speed sensors They are designedprimarily to provide an easy means of attaching a pulsegenerating assembly to rotating shafts Sensor gap-ping shaft run-out and mounting problems are elimi-nated This makes the unit especially useful for shaftswith high run-out The ordering map on the followingpage provides information for selecting a unit for yourparticular application Please note that sensors andcable assemblies must be ordered separately

Taper-Lockreg Type

enables quick attachment to rotating shafts Thetransducer employs a rotor with small perforationsalong its periphery a permanently lubricated sealedbearing an outer ring and a reference rod whichwhen clamped in position prevents the outer ringassembly from moving The outer ring canaccomodate up to three speed sensors for use inmonitoring directions of rotation and speed

Sleeve Type

identical to the Taper-Lock type except that it providesa sleeve bushing with two set screws for installationpurposes allowing larger shaft sizes

It is the customers responsibility to determinewhether the product is proper for customers use andapplication

The assembly consists of a Taper-Lock bushing which

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

It is the customers responsibility to determine whether the product is proper for customers use and application

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Tachometer Transducers

when used with speed sensors They are designedprimarily to provide an easy means of attaching a pulsegenerating assembly to rotating shafts Sensor gap-ping shaft run-out and mounting problems are elimi-nated This makes the unit especially useful for shaftswith high run-out The ordering map on the followingpage provides information for selecting a unit for yourparticular application Please note that sensors andcable assemblies must be ordered separately

Taper-Lockreg Type

enables quick attachment to rotating shafts Thetransducer employs a rotor with small perforationsalong its periphery a permanently lubricated sealedbearing an outer ring and a reference rod whichwhen clamped in position prevents the outer ringassembly from moving The outer ring canaccomodate up to three speed sensors for use inmonitoring directions of rotation and speed

Sleeve Type

identical to the Taper-Lock type except that it providesa sleeve bushing with two set screws for installationpurposes allowing larger shaft sizes

It is the customers responsibility to determinewhether the product is proper for customers use andapplication

The assembly consists of a Taper-Lock bushing which

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

when used with speed sensors They are designedprimarily to provide an easy means of attaching a pulsegenerating assembly to rotating shafts Sensor gap-ping shaft run-out and mounting problems are elimi-nated This makes the unit especially useful for shaftswith high run-out The ordering map on the followingpage provides information for selecting a unit for yourparticular application Please note that sensors andcable assemblies must be ordered separately

Taper-Lockreg Type

enables quick attachment to rotating shafts Thetransducer employs a rotor with small perforationsalong its periphery a permanently lubricated sealedbearing an outer ring and a reference rod whichwhen clamped in position prevents the outer ringassembly from moving The outer ring canaccomodate up to three speed sensors for use inmonitoring directions of rotation and speed

Sleeve Type

identical to the Taper-Lock type except that it providesa sleeve bushing with two set screws for installationpurposes allowing larger shaft sizes

It is the customers responsibility to determinewhether the product is proper for customers use andapplication

The assembly consists of a Taper-Lock bushing which

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

ApplicationUsed for Speed Take Off

The Side Look Sensor (SLS) has been developed byAI-Tek Instruments for Allison automatic transmis-sions for trucks ranging from light duty vans to over-the-road tractors It is available for Allison AT MTand HT transmissions The new SLS improves onearlier designs developed for Allison to replace amechanical speed system

The SLS is a variable reluctance device that pro-vides electronic transmission speed inputs toengine control systems andor electronic dash-boards It mounts directly on the transmission andemploys a unique magnet configuration thatinduces a magnetic field on the side of the sensorin the path of the rotating transmission gear Thissystem with its fewer mounting parts improvesreliability reduces weight and conserves spaceover the earlier designs

AI-Tek Instruments LLCSide Look Sensor

The new SLS uses a molded glass filled nylon bodyto protect the sensor in harsh truck-operatingenvironments It replaces the old fly-lead designwith an integral standard Packard connectorwhich eliminates the added extra connector cost ofthe old design It is available in single and dualoutput versions

The SLS is manufactured in the United StatesAI-Tek Instruments Distributors stock the SLS foroff-the-shelf maintenance repair and overhaul(MRO) requirements

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Hall Effect Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for engine timing applications and has developed a line of durable products for

industrial use

With multiple standard variations we offer the widest range of standard catalog

sensors to meet your various design needs The design is flexible to easily meet all

of your application requirements

The Hall Effect sensor can sense each change in target movement regardless of speed

from near zero to 15 kHz frequency range generating a steady pulse train of frequency

proportional to target speed Typically each time a gear tooth (or any ferrous discontinuity)

passes in front of the sensor the output changes state This type of sensor is known as a P

type because it uses N-P-N transistor logic (as opposed to N type which uses P-N-P

transistor logic)

Key features to note are

bull Reverse voltage protection to prevent damage if miswired

bull Extended temperature range

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

AI-Tek has (3) Series of Hall Effect Sensors RH Series DH Series and BH Series

Below is a quick reference chart of the features of each of the series

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

Key features

bull Reverse voltage protection to prevent damage if miswired

bull Wide range of supply voltage

bull Two output options of Supply Tracking or TTL Compatible

bull Rugged design meeting IEC 77 Standards (European Railroad Applications)

bull Require special alignment

bull Improved duty cycle

bull Improved fine pitch performance

bull Increased air gaps

Suitable for 32 diametral pitch or coarser gear (target) the standard catalog

sensors are easily applied to your various sensing needs If you have a unique special

requirement which cannot be met with any of the standard options we will gladly review your

specs and work with you on a special sensor design

It is the customers responsibility to determine whether the product is proper for customers use and application

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

DH SERIES

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect

sensors for harsh applications and has developed a line of durable products for industrial rail

military and automotive use

The new Al-TEK DH series sensors are differential based zero-speed precision single

channel speed sensors At power-up they calibrate themselves to the unique magnetic

signature of their installed application and continue to update the calibration as the sensor is

running This unique combination of differential sensing technology and calibration make these

sensors highly tolerant of installation mis-alignment target geometry and composition target

run-out vibration and air gap changes

In comparison the RH series are single-element based zero speed single channel speed

sensors and are an excellent choice for general purpose speed sensing Unlike the DH series

that requires rotational alignment at installation the RH requires no alignment Air gap

adjustment is precise and easy and similar to a VR type sensor

The new DH sensor can sense each change in target movement regardless of speed

from zero to 15 kHz frequency range generating a steady pulse train of frequency proportional

to target speed Typically each time a gear tooth (or any ferrous discontinuity) passes in front of

the sensor the output changes state This type of sensor is known as a P type because it uses

N-P-N transistor logic (as opposed to N type which uses P-N-P transistor logic)

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

AI-Tek Bi-directional zero velocity sensors are self-calibrating to the specific customer

application and provide two independent frequency outputs and a direction signal output to

indicate change in direction of the sensed ferrous target

The Bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two

Hall effect sensing elements physically offset from each other Each element generates a single

channel of target information identical in frequency and polarity but offset in the time domain

(phase shifted) Special circuits inside the sensor are designed to calibrate each channel to its

application target then analyze these two channels of information for a phase lead lag

condition The direction output will then provide a logic 1 level for clockwise or a logic 0 for

counterclockwise rotation assuming proper sensor orientation

It is the customerrsquos responsibility to determine whether the productis proper for customerrsquos use and application

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Tachometer Transducers

when used with speed sensors They are designedprimarily to provide an easy means of attaching a pulsegenerating assembly to rotating shafts Sensor gap-ping shaft run-out and mounting problems are elimi-nated This makes the unit especially useful for shaftswith high run-out The ordering map on the followingpage provides information for selecting a unit for yourparticular application Please note that sensors andcable assemblies must be ordered separately

Taper-Lockreg Type

enables quick attachment to rotating shafts Thetransducer employs a rotor with small perforationsalong its periphery a permanently lubricated sealedbearing an outer ring and a reference rod whichwhen clamped in position prevents the outer ringassembly from moving The outer ring canaccomodate up to three speed sensors for use inmonitoring directions of rotation and speed

Sleeve Type

identical to the Taper-Lock type except that it providesa sleeve bushing with two set screws for installationpurposes allowing larger shaft sizes

It is the customers responsibility to determinewhether the product is proper for customers use andapplication

The assembly consists of a Taper-Lock bushing which

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Tachometer Transducers

when used with speed sensors They are designedprimarily to provide an easy means of attaching a pulsegenerating assembly to rotating shafts Sensor gap-ping shaft run-out and mounting problems are elimi-nated This makes the unit especially useful for shaftswith high run-out The ordering map on the followingpage provides information for selecting a unit for yourparticular application Please note that sensors andcable assemblies must be ordered separately

Taper-Lockreg Type

enables quick attachment to rotating shafts Thetransducer employs a rotor with small perforationsalong its periphery a permanently lubricated sealedbearing an outer ring and a reference rod whichwhen clamped in position prevents the outer ringassembly from moving The outer ring canaccomodate up to three speed sensors for use inmonitoring directions of rotation and speed

Sleeve Type

identical to the Taper-Lock type except that it providesa sleeve bushing with two set screws for installationpurposes allowing larger shaft sizes

It is the customers responsibility to determinewhether the product is proper for customers use andapplication

The assembly consists of a Taper-Lock bushing which

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Digital Signal Distance Amplifier

(DSDA)

The newest member of the AI-Tek family

The new AI-TEK DSDArsquos are designed for

use with active sensors and serve to reduce

line impedance allowing cable runs of up to

3000ft In some cases this represents a 10X

improvement over installations not currently

using a DSDA

Line impedance plays a major role in the distance an active sensor signal can be transmitted

through cable and wire Mutual capacitance of 25 Pico-faradsfoot or more can exist between

conductors When sufficient resistance from the sensor cabling and output load is placed in

series with that capacitance signal rise times can increase to the point where the sensor can

no longer switch This condition becomes even worse due to higher target speeds that cause

output signal frequency rises

Two versions were developed to allow use with either TTL or supply tracking output options

The DSDA will work with any AI-TEK active sensor and many other brands that support these

output styles

Construction is rugged Each DSDA is potted into a cast aluminum box Cables enter the box

through weather-tight strain relief bushings and allow all cable connections including shield

to be terminated inside the box

Tachometer Transducers

when used with speed sensors They are designedprimarily to provide an easy means of attaching a pulsegenerating assembly to rotating shafts Sensor gap-ping shaft run-out and mounting problems are elimi-nated This makes the unit especially useful for shaftswith high run-out The ordering map on the followingpage provides information for selecting a unit for yourparticular application Please note that sensors andcable assemblies must be ordered separately

Taper-Lockreg Type

enables quick attachment to rotating shafts Thetransducer employs a rotor with small perforationsalong its periphery a permanently lubricated sealedbearing an outer ring and a reference rod whichwhen clamped in position prevents the outer ringassembly from moving The outer ring canaccomodate up to three speed sensors for use inmonitoring directions of rotation and speed

Sleeve Type

identical to the Taper-Lock type except that it providesa sleeve bushing with two set screws for installationpurposes allowing larger shaft sizes

It is the customers responsibility to determinewhether the product is proper for customers use andapplication

The assembly consists of a Taper-Lock bushing which

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Tachometer Transducers

when used with speed sensors They are designedprimarily to provide an easy means of attaching a pulsegenerating assembly to rotating shafts Sensor gap-ping shaft run-out and mounting problems are elimi-nated This makes the unit especially useful for shaftswith high run-out The ordering map on the followingpage provides information for selecting a unit for yourparticular application Please note that sensors andcable assemblies must be ordered separately

Taper-Lockreg Type

enables quick attachment to rotating shafts Thetransducer employs a rotor with small perforationsalong its periphery a permanently lubricated sealedbearing an outer ring and a reference rod whichwhen clamped in position prevents the outer ringassembly from moving The outer ring canaccomodate up to three speed sensors for use inmonitoring directions of rotation and speed

Sleeve Type

identical to the Taper-Lock type except that it providesa sleeve bushing with two set screws for installationpurposes allowing larger shaft sizes

It is the customers responsibility to determinewhether the product is proper for customers use andapplication

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Sensor Mounting BracketsSeveral types of brackets are available to facilitate

the mounting of AI-Tek speed sensors Threadedbrackets for 38-24 58-18 and 34-20 threads aregenerally used with passive sensors with one locknutActive zero- velocity sensors and passive chisel-pointsensors that require specific alignment should be usedwith unthreaded brackets and two locknuts

Bracket material is non-magnetic 303 stainlesssteel locknuts are also non-magnetic stainless steel orplated brass

Sensors and brackets should be attached to aframe free of excessive vibration to prevent spuriousindications when the gear is stopped or turning at veryslow speeds Refer to sensor specifications for properair gap and alignment with gear (target) rotation

Caution Too small an air gap especially with excessive run-out may cause the gear tostrike the sensor and make it inoperative

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance

Principles of Operation

The internal construction of the typical

Al-Tek variable reluctance sensor is a magnet

pole piece and coil (See figure 1) A magnetic

field (lines of flux) extends from the magnet

through the pole piece and coil out into the air

space at the end of the sensor The return path of

the magnetic field is from the air space to the

other end of the magnet As a ferrous object ap-

proaches the tip of the pole piece the magnetic

field increases and then decreases as the object

moves away from the pole piece The snap or the

rapid change in the magnetic field induces an AC

voltage signal in the coil With an ideal target and

matching sensor the induced voltage is in the shape of a sine wave

As can be seen the generated frequency signal is directly proportional to the number of ferrous

objects passing the pole piece per unit time The amplitude of the voltage output is proportional to

the speed of the ferrous objects passing the pole piece

Many applications of Al-Tek magnetic sensors use gears as targets Typical sensor output wave

forms with various targets are illustrated in Figure 3 Testing sensors with gears rather than other

ferrous discontinuities such as sprockets keyways boltheads etc is because the output is

predictable and repeatable See Figure 2 for commonly used gear terminology

Diametral Pitch = No of Teeth + 2

Outside Dia of Gear (in)

The performance of a sensor can be easily

defined when using a gear for a target it also

allows for estimated performance with alternate

targets Al-Tek sensors are tested with AGMA

standard gears the performance curves are

included in this catalog

Al-Tek Instruments differs from most sensor

manufacturers in the presentation of performance

curves and test parameters Most existing data is

specified at a surface speed of 1000 insec and

0005 in air gap we feel that a 0030 in air gap

and 500 in sec surface speed (1800 RPM motor

with 5 to 6 in dia gear) are more realistic

parameters to specify performance
