RMS and peak velocity loop
powered sensors
PC420V series
Wilcoxon’s PC420V series sensors provide a 4-20 mA output proportional to
velocity vibration, allowing for continuous trending of overall machine vibration.
This trend data alerts users to changing machine conditions and helps 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 requirements.
