PC420 Explosion proof acceleration LPS™
PC420Ax-yy-Ex, top exit 4-20 mA loop powered sensor

The output of the PC420A series is proportional to acceleration vibration. An output of 4 mA indicates a level of 0 g or no vibration present. A full-scale reading of 20 mA indicates the maximum range (Peak or RMS) of vibration is present. The Peak output units provide a computed equivalent peak level of vibration based on the RMS.

Benefits Choice of output: RMS, True Peak, and Peak, permits you to choose the sensor that best fits your industrial requirements Provides continuous trending of overall machine vibration True peak is useful for detecting loose parts like valves on reciprocating machinery Can help guide maintenance Helps notify of impending equipment failure Hazardous area installation	Features Peak equivalent or RMS or True Peak Explosion proof certification Corrosion resistant ESD protection Overload protection Reverse wiring protection
