Model PC420ATP Series True Peak Acceleration Loop Powered Sensor
Brand: Wilcoxon Sensing TechnologiesWilcoxon’s PC420ATP series 4-20 mA vibration sensors provide 24/7 output of true peak acceleration for trending in PLC systems, alerting users to changing machine conditions and helping to guide maintenance in prioritizing the need for service. True peak is useful for detecting loose valves, rod knock and piston slap on reciprocating machinery.
The 4-20 mA output of the PC420ATP series is proportional to true peak 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 of vibration is present.
