Pump cavitation detected using a Wilcoxon sensor

2022-07-12

●A pump manufacturer used a Wilcoxon vibration sensor on a positive displacement pump and found that the sensor successfully detected cavitation. Early detection of cavitation can minimize damage, reduce downtime, and save money.
●The picture shows the location of the Wilcoxon sensor. The PC420ATP-05-B3223 is a loop powered sensor (LPS™) that provides a 4-20 mA output signal proportional to the overall vibration level of the pump. Process control systems, such as a PLC or DCS, commonly accept this type of input. The PC420ATP-05-B3223 is an acceleration, true peak detection, frequency banded vibration sensor chosen because it is best suited to monitor the regular and irregular vibrations of the positive displacement lobe pump.
●The pump was run at 359 RPM and had a vacuum pump connected to the input line. The vacuum pump was used to initiate cavitation conditions.
