A pump cavitation sensor at last!

The ifm electronic pump diagnostic pressure sensor detects cavitation, trapped air and blockages, just what you have been waiting for!

Sensor market leader ifm electronic has come up with another stunning new product with a new line of pump diagnostic pressure sensors that can detect and warn of the potential pump damage caused by cavitation, trapped air or gas, blockages and deposits.

The PIM Series pressure sensor can perform two functions in one compact housing: pump monitoring and pressure detection.

The sensor continuously monitors a pump to provide numeric indication of the operating system pressure and offers independent continuous diagnosis of the pump condition.

Operating as a pump diagnostic sensor, the PIM sensor measures the high-frequency pulsation of a properly operating pump and stores it as a reference.

If changes occur in the system, the pulsations will change.

These changes are immediately detected by the sensor.

If a critical pump condition occurs, such as cavitation, the sensor will provide an alarm signal to a controller.

The ifm condition-based pump monitoring sensor increases machine up-time and reduces damage caused by poor pump operating conditions.

In addition to 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.

The sensor and its teach function are quickly set up using the numeric pushbutton display.

The sensor has a display that alternately provides the numeric system pressure and the operating state of the pump as a trend, that graphically depicts the operating state of the pump.

The second output of the sensor can be configured as a switching output with hysteresis or window function or as a scalable analogue output.

Due to the high overload resistance of the ceramic capacitive measuring cell, the sensor is especially suited for switch-off in case of overpressure.

FDT programming software enables the display of the measured values, analogue output, limit values and the parameter setting of the thresholds for diagnosis.

The stainless steel PIM pressure sensor is designed for sanitary applications and uses a variety of sanitary adapters for a secure fitting in washdown, CIP and SIP conditions.

The sensor is 3A authorised and meets FDA and EHEDG requirements.

A variety of M12 cable assemblies designed specifically for wash-down conditions are available from ifm.
