Industrial High Temperature 4-20 mA Vibration Sensors

Germantown, MD -- Wilcoxon Research, a Meggitt Group company and a leading supplier of quality accelerometers and sensor networks, has improved the performance of several popular 4-20 mA vibration sensors to operate in high temperature environments up to 105° C (221° F). Sensors with the new, higher temperature rating have a velocity or acceleration 4-20 mA output based upon RMS or Peak.

The 4-20 mA vibration sensor models beginning PC420AR (acceleration RMS), PC420AP (acceleration peak), PC420VR (velocity RMS), and PC420VP (velocity peak) were redesigned to perform at operating temperatures up to 105° C (221° F). "Our customers require vibration sensors designed to withstand the harsh industrial environment," said Tom Smith, Vice President of Sales and Marketing. "These sensors make affordable vibration trending available to customers with high temperature applications."

Wilcoxon's 4-20 mA sensors monitor rotating equipment and output a real time 4-20 mA signal proportional to the vibration level. By trending this real time data, plant personnel are able to schedule preventative maintenance activities around planned downtime, saving time and money in costly unexpected repairs. Integrating this signal into an existing PLC, DCS or SCADA system simplifies real time health monitoring because vibration, formerly considered too complex, can now be trended in easily understood units.

A wide variety of 4-20 mA vibration sensors are available to suit individual monitoring needs. Sensors are available with: top exit or side exit connectors; Intrinsically Safe and Explosion Proof ratings; monitoring acceleration, velocity or displacement; output based upon root-mean-square, peak, true-peak, or true peak-to-peak; and dual monitoring of vibration and temperature. Not all of Wilcoxon's 4-20 mA vibration sensors are rated to 105° C (221° F). Applications for Wilcoxon's 4-20 mA vibration sensors include compressors, motors, vibrating conveyors, seal-less pumps, chillers, gearboxes, pumps, exhaust fans, reciprocating compressors, blowers, cooling towers, mixers, gas/steam turbines and centrifuges.
