Sensors for Monitoring Pumps and Submersible Pumps

Hermetic sensors used for protection against pump cavitation, recirculation, and resonance

There are dozens of different types of pumps and a seemingly endless list of applications but industrial accelerometers can often help the maintenance professional to diagnose sometimes tricky issues with pump operation. Using vibration monitoring in your predictive maintenance program can help identify pump problems such as cavitation, recirculation and resonance.

A good rule of thumb is to select an accelerometer that has a linear high frequency response capability to three times the pump's vane pass frequency (vane pass frequency = # of vanes x RPM). Most general purpose accelerometers will have more than adequate high frequency response and thus the next key is selecting a transducer that will survive the application. For this purpose IMI® has a wide range of submersible accelerometers as well as sensors and cabling that will survive in corrosive environments.
