Pump sensor detects potential damage

Industrial control specialists IFM Efector Inc has launched a line of pump diagnostic pressure sensors that can detect potential pump damage caused by cavitation, trapped air or gas, blockages and deposits. The PIM Series pressure sensor can perform pump monitoring and pressure detection. The sensor continuously monitors a pump to provide numeric indication of the operating system pressure while offering independent continuous diagnosis of the pump's condition.

Operating as a pump disgnostic sensor, the PIM sensor can measure the high-frequency pulsations of a properly operating pump and stores it as a reference. If changes occur in the system, the pulsations will change - which is immediately detected by the sensor. If a critical pump condition occurs, such as cavitation, the sensor will provide an alarm signal to a controller.

As well as monitoring a pump, any disturbances around the pump such as trapped air in the medium, clogged filters, deposits in pipes or improperly opened valves are also monitored.
