PC420A Series RMS & Peak Acceleration Loop Powered Sensor

Brand: Wilcoxon Sensing Technologies
Request Information
Favorite
Wilcoxon’s 4-20 mA vibration sensors integrate easily with an existing PLC, DCS or SCADA system. The PC420A series provides 24/7 output of overall machine vibration for trending in PLC systems, alerting users to changing machine conditions and helping to guide maintenance in prioritizing the need for service. The choice of RMS or peak output allows you to choose the sensor that best fits your industrial requirements.

The 4-20 mA 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 that the maximum range (RMS or peak) of vibration is present.
Features
  • Choice of true RMS or calculated peak output
  • Corrosion resistant
  • Hermetically sealed
  • ESD protection
  • Overload protection
  • Reverse wiring protection
