Digital Proximity System

Opera� on and Maintenance Manual

100576 • REV B

The DPS (Digital Proximity System) family

consists of two devices, the MX2033 and

MX2034. The MX2033 is a conven� onal

3-wire driver while the MX2034 is a two-

wire current loop transmi! er. Users can con-

fi gure either unit to measure peak-to-peak

vibra� on, gap distance, or rota� onal speed.

These products are used in conjunc� on with

a proximity probe and extension cable to

measure the vibra� on levels, gap distances,

or rota� onal speed of machinery sha# s.

Users can also confi gure the units via a USB

cable and confi gura� on so# ware.

The sec! ons below provide more module informa! on.

2.1 MX2033 THREE�WIRE PROXIMITY DRIVER

The MX2033 signal output is propor! onal to the distance between the probe ! p and the

target material. The signal output follows API Standard 670 and is compa! ble with most

con! nuous vibra! on monitoring systems. The MX2033 uses -24Vdc excita! on and provides

an output scale factor of 7.87 mV/mm (200mV/mil) for 5 mm and 8mm probes.

2.2 MX2034 TWO�WIRE TRANSMITTER

The MX2034 provides an ISA standard 4-20 mA signal propor! onal to vibra! on or axial posi-

! on for direct connec! on to a PLC, DCS, SCADA system, or other instrumenta! on without

requiring a separate monitor system. The MX2034 is powered by +24 Vdc, supplied within

the current loop. The MX2034 is user-programmable to func! on as either a radial vibra! on

transmi" er (where the 4-20 mA signal is propor! onal to peak-peak vibra! on amplitude), or

as an axial posi! on transmi" er (where the 4-20 mA signal is propor! onal to average probe

gap). For convenience when connec! ng to signal analyzers, portable data collectors, and test

instrumenta! on, the raw vibra! on signal is available at a short-circuit protected BNC con-

nector. Refer to sec! on 3.6 of this manual for important informa! on and cau! ons regarding

proper use of this connector.

rently supports two measurements: Radial Vibra! on and Axial Posi! on.

3.5.4.4.1 RADIAL VIBRATION

The MX2034 performs a peak to peak detec! on and drives the 4-20 mA output as a percent-

age of the confi gured range.

1) Select the new confi gura! on

parameters from the drop down list

2) Click the Send bu$ on to send the new

confi gura! on to the DPS

Doc# 100576 • REV B (April 2015) of 42

3.5.4.4.2 AXIAL POSITION

age of the confi gured range.

3.5.4.5 RANGE

The Range choices are diff erent for Radial Vibra" on and Axial Posi" on measurements.

3.5.4.6 4!20mA DIRECTION

The MX2034 allows confi gura" on of upscale or downscale for the 4-20mA output. Upscale

means that for the range selected in 3.5.4.5, 4mA corresponds to bo% om of scale and 20mA

corresponds to top of scale; downscale reverses these conven" ons and means that 20mA

corresponds to bo% om of scale and 4mA corresponds to top of scale.

clear window. A" ach both labels to the side of the DPS unit. Refer to DPS Label Kit manual

100528 for addi! onal details.

3.6 USING THE MX2034 BUFFERED OUTPUT

Due to the two wire, loop-powered MX2034 transmi" er design, the current loop common

fl oats on top of the voltage developed across the current loop sense resistor.

Doc# 100576 • REV B (April 2015) of 42

The buff ered output common is protected against ground loop currents aff ec" ng the current

loop output with a 10kΩ resistance between the buff ered output common and the loop

common.

Metrix recommends using a ground isolated instrument or signal isolator. The meter, oscil-

loscope or analyzer used to measure the gap voltage or to observe the vibra" on signal

(DYNAMIC OUTPUT) must have an input impedance of one megohm or greater.

The scale factor of the output signal is 200 mV/ mil.

Metrix recommends a maximum cable length of 15 % (5 m) when connec" ng to the buff ered

output due to noise suscep" bility caused by the high input and output impedances.

4. VERIFICATION AND CALIBRATION

This sec" on describes the steps to verify proper DPS opera" on and to custom calibrate your

DPS to your specifi c probe and cable.

CAUTION: When using the MX2034 BNC connector, exer-

cise special care to prevent ground loops that could alter

the 4-20mA output, resul" ng in spurious alarms or ma-

chine trips. Such ground loops can occur when connec" ng

to grounded test equipment or mul" ple input test equip-

ment. Metrix recommends use only with ungrounded test

equipment, such as ba' ery-powered portable meters,

or grounded test equipment with diff eren" al inputs (i.e.,

neither side of input connec" on is " ed to ground). Also,

cable lengths between the BNC connector and test equip-

ment should be kept suitably short (5m or less) to prevent

unwanted noise.

NOTE: The DPS requires the probe and extension cables be

from the confi gured probe series, combine to the confi g-

ured system length, and view the confi gured target mate-

rial in order to meet system range and accuracy

Doc# 100576 • REV B (April 2015) of 42

4.1 SCALE FACTOR VERIFICATION

Follow these steps in this sec! on to verify the voltage output scale factor. The basic proce-

dure is:

Obtain the correct target material

Assemble the test instruments and equipment

Electrically zero the probe

Measure the output voltage in fi xed gap increments

4.1.1.1 OBTAINING THE TARGET

Use a 1.2 inch or larger target with 5 mm or 8 mm probes. Be sure your target material

matches the material the DPS calibra! on material. To verify the calibra! on material, follow

the steps listed in Figure 16.

4.1.1.4 MEASURE THE VOLTAGE IN GAP INCREMENTS

Increase the micrometer 10 mil (0.25 mm) increments and fi ll in the measured SIG Voltage in

the table below.

Table 4: Verifi ca" on Data Table

mils mm SIG Voltage

10 0.25

20 0.50

30 0.75

40 1.00

50 1.25

60 1.50

70 1.75

80 2.00

90 2.25

To calculate the Average Scale Factor (ASF), subtract the voltage measured at 10 mils (0.25

mm) from the voltage at 90 mils (2.25 mm)and divide by the full scale range of 80 mils (2

mm)

Example:

Voltage at 90 mils (2.25 mm) is -17.1 V


ASF = (-0.98) - (-17.1)/80 = 201.5 mV/mil

Or

ASF = (-0.98) - (-17.1)/2 = 8.06 mV/mm

To calculate the Incremental Scale Factor (ISF) at each gap, subtract the SIG voltage mea-

sured 10 mils (0.25 mm) below each increment and divide by 10 mils (0.25 mm).

Example:



ISF = (-9.02) - (-7.1)/10 = -192 mV/mil

Or

ISF = (-9.02) - (-7.1)/0.25 = -7.68 mV/mm

4.2 SCALE FACTOR CUSTOM CALIBRATION

You can easily custom calibrate the DPS for your probe following the procedure in this sec-

! on. Perform the Scale Factor Verifi ca! on as described in sec! on 4.1.

Open the DPS so$ ware and click the bu% on.

The custom calibra! on window opens.

Enter the voltages measured at each gap from the Scale Factor Verifi ca! on data.

When complete, click the Generate and Load Lineariza! on bu% on. The so$ ware will adjust

the DPS lineariza! on to match the probe and cable.

NOTE: The custom calibra! on process overwrites any

previous custom calibra! on. Standard Metrix factory

calibra! ons for MX2030 and 7200 5m and 9m systems are

not aff ected.

Figure 21: Custom Calibra� on Successful Comple� on

If the probe and cable run very far out of specifi ca! on, the DPS may not be able to linearize

the curve. In this case, the so$ ware will show an error message as shown in Figure 22.

Fill in the voltages measured at each gap

and then click the Generate and Load

Lineariza! on bu% on.

Figure 22: Custom Calibra� on Shortened Curve

If this occurs, verify that the voltages you entered were correct. Verify that your system

components combine to the correct length. If all is correct, you can choose to accept the

shortened curve or hit cancel and use a diff erent probe and cable. In some cases, probes

and cables that are far out of specifi ca$ on can be brought into specifi ca$ on by itera$ ng the

custom calibra$ on process several $ mes.

4.2.1 CURRENT LOOP VERIFICATION !MX2034 ONLY"

Follow the steps in this sec$ on to verify the current loop output for Posi$ on or Radial Vibra-

$ on confi gured DPS units.

4.2.1.1 POSITION CONFIGURED UNITS

The transmi% er current output is linearly propor$ onal to the average probe gap (posi$ on)

between 4 mA and 20 mA. Use the instruments and equipment shown in Figure 23 to verify

a posi$ on transmi% er current output.

NOTE: Metrix does not recommend using the custom

calibra$ on feature to calibrate mismatched systems. Mis-

matched systems degrade probe and cable temperature

performance.

Doc# 100576 • REV B (April 2015) of 42

Figure 23: Current Loop Valida� on Set Up

At each gap, measure and record the SIG Voltage from the volt meter and the current output

measured by the Ammeter.

mils mm SIG Voltage Current

10 0.25

20 0.50

30 0.75

40 1.00

50 1.25

60 1.50

70 1.75

80 2.00

90 2.25

Use the following equa! on to determine the expected current at each gap.

Current = 16 * (Gap-Bo" om Scale Gap) / (Top Scale Gap-Bo" om Scale Gap) + 4mA

Doc# 100576 • REV B (April 2015) of 42

Example: The confi gured range is 10 to 90 mils and the current gap is 30 mils.

Bo" om Scale Gap = 10 mils

Top Scale Gap = 90 mils

Current = 16 * (30 -10) / (90-10) ) +4mA = 8mA

NOTE: Tolerance is + 0.15 mA.

4.2.1.2 RADIAL VIBRATION

The transmi" er current output is linearly propor$ onal to the full scale vibra$ on range

between 4 mA and 20 mA. The following equa$ on represents the rela$ onship between the

vibra$ on and the loop current:

Vibra$ on = (Current (mA) -4) / 16 * (Full Scale Range)

EXAMPLE:

Measured mA Full Scale Vibra! on Actual Vibra! on

<3.6 5.0 mils, pk-pk Probe Fault

4.0 5.0 mils, pk-pk 0.0 mils, pk-pk
