Wilcoxon Research's redesigned 4-20 mA vibration sensors operate in high-temperature environments

Wilcoxon Research has improved the performance of several 4-20 mA vibration sensors to operate in high-temperature environments up to 105°C (221°F). Sensors with the 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).

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 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 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.
