Selection Process – 1. Electrical Rating




2. Control Signal Type

The Signal type is dependent on the end user’s process control system and the I/O cards used

• Traditional feedback signals are line voltage AC, around 500 mA– SPDT contact types typically used– Standard mechanical switches are sufficient– Tungsten TTL proximity switches are also acceptable– Voltage and current fluctuations/spikes from unconditioned line power require

switches that can handle the application• Newer control systems are using low current/low voltage DC signals as low

as 8 V and 20 mA– Gold plated mechanical switches (low cost option) – Rhodium TTL switches are the best chopice

• Standard mechanical switches are not recommended as the silver contacts can tarnish, increasing contact resistance

• Tungsten switches have a high contact resistance to begin with

Selection Process – 2. Signal Type




• Custom feedback applications – Redundant feedback switching (4 SPDT switches)– DPDT switches combining feedback and local relay control – 3 wire DC PNP or NPN sensors– 2 wire sensors with parameters specific to the control cards used– Pneumatic switches

• Valve Networking with ASi, DeviceNet, Profibus or Foundation Fieldbus protocols

– To be reviewed in a later section





Passive Switch Types





Basic Sensor Types





3. Installation Environment

The most overlooked concern, leading to the most failures• Dry, indoor environments with constant temperature

– The least challenging for VPTs

• Mechanical SPDT switches with silver contacts, aluminum enclosures acceptable

• Outdoor environments

– Condensation will collect inside enclosure

• Aluminum flanges and silver contacts will corrode

• Corrosive Environments

– Caustic wash down

– Valves with corrosive chemicals with leak vapors, vapors will combine w/ condensation and create a corrosive liquid

– Outdoor salt water

• These applications require specific constructions

» Plastic enclosures, encapsulated switches, anodized aluminum for explosion-proof applications

• Hot (boiler / furnace room) environments

– Use special switches designed for high temperature

Field Experience: Valve position indicator is

not rugged enough for the industrial environment

Solution: The Rugged Moniteur Indicator• No screws or flanges prevent cover from cracking in the field

under hard use • Delrin® drive system allows a rated life of 1,000,000 cycles • NO failures in over 250,000 units installed




Solution: The Moniteur Setting Ring• Fully 360º adjustable for all valve and actuator types • Indicator sits on pins 180º apart, preventing incorrect

mounting• Clear cover has no decals or paint that must be “aligned”

with the indicator drum

Field Experience: Visual position indication does not

match electrical indication and / or cannot adjust

properly to the valve or actuator

The Moniteur Indicator

Solution: Moniteur’s extensive range of indicators• 3-way path O, T and F• 4 way path S• 180 degree 3-way path T and L• 0-100% digital indicator

Hermetically Sealed Non-Contact Reed SwitchesExcel In Aggressive Environments

•Tungsten TTL SPDT- Tungsten elements provide high current handling capability to 3A / 120VAC. The choice for AC feedback signals.

•Rhodium TTL SPDT / SPST - Rhodium elements are rated 1A at 24VDC,for low current / voltage DC control signal applications (less than 20ma). MTBF > 1,000,000 cycles, contact resistance 1/5 of Tungsten

•Bifurcated TTL SPST switches made popular by theirexcellent low current handling capability - 5mA @ 5V.

•Krystal TTL SPDT - LED Set Lights plus Rhodium elements provide 0.3A current rating at 24VDC or 120 VAC. TTL switches are driven by a nickel plated magnet encapsulated in the

cam mounted on the shaft. The magnet trips the switch element enclosed in the switch housing. Moniteur’s patented loc-ring shaft retention system insures reliable output signals.

Non-Contact “Proximity” Switches

•Choose TTL Switches for damp, humid or corrosive environments, low current feedback signals and high cycling applications where signal reliability is critical to the process. •TTL Switches are hermetically sealed and can be used in Division 2 - Groups A, B, C & D environments without conduit seal fittings.




Inductive Sensors are solid state (no moving parts) and constantly provide a feedback signal. They are the most reliable sensor type, with a MTBF of over 20 million cycles. When the metallic trigger enters the sensor’s magnetic field, the signal strength changes. This signal differential is used to indicate valve position.

•Pepperl & Fuchs popular NJ2-V3 NAMUR sensor is FM approved Intrinsically Safe and is specified at plants worldwide. NBB2-V3-Z4, NBB2-V3-US, and SJ1.5-SN/S1N sensors are also available

•Efector NS 5003 NAMUR sensor is also FM approved Intrinsically Safeand includes setting lights built into the sensor

Inductive Sensors

Choose Inductive Sensors for applications requiring 2-wire sensor output. Because they consume power during normal operation, Inductive Sensors can and must have Intrinsically Safe approval to be used in a hazardous area.

Inductive Sensors match your advancedProcess Control System




Common Switch Problems

Field Experience: Intermittent feedback signals due to switch corrosion

Cause: Switch not chosen for corrosive applications

Solution: Choose switch for environment• Hermetically Sealed TTL Non-Contact switches can replace SPDT

mechanical switches with no change in wiring or programming• Hermetically Sealed Inductive Sensors

Field Experience: Intermittent feedback signals - DC control signals

Cause: Switch not suitable for low level DC signals

Solution: Choose Rhodium TTL Proximity Switches• Standard Tungsten contacts are not stable for low current, low voltage DC signals• Due to low contact resistance, Rhodium TTL proximity switches can handle signals

as low as 5ma @ 5VDC.

Field Experience: Intermittent feedback signals

Cause: Cams not set properly

Solution: Set cams with a meter and not by eye - this is a common problem
