ifm efector  has launched a new line of pump diagnostic pressure sensors that detect potential pump damage caused by cavitation, trapped air or gas, blockages and deposits.

PIM 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’s condition.

Operating as a pump diagnostic sensor, the PIM sensor measures 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. 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.

ifm efector’s condition-based pump monitoring sensor increases machine uptime 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 diagnostic function of efector PIM enables safe operation of pumps and systems. Due to the continuous monitoring of pumps and machines, the sensor can be perfectly integrated into condition-based concepts. This permits longer maintenance intervals, which in turn leads to lower costs.

Expensive consequential damage caused by the failure of pumps is avoided and, notably, environmental stress (sometimes associated with extreme consequential costs) is prevented. By integrating maintenance into a real-time-maintenance concept it can be implemented at the right time, in the right place, using the right material and staff.

The sensor and its teach function are quickly setup using the numeric pushbutton display. The sensor’s display alternately provides the numeric system pressure and the operating state of the pump via a trend display that graphically depicts the operating state of the pump.

The sensor’s second output can be configured as a switching output with hysteresis or window function or as a scaleable 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, analog output, limit values and the parameter setting of the thresholds for diagnosis.

The stainless steel PIM pressure sensor is designed for sanitary applications. A variety of M12 connectors suitable for these conditions are available from ifm.

ifm efector provides customers with German engineered and manufactured sensor and control solutions for automation. ifm efector’s product ranges include position sensors and object recognition, fluid sensors and diagnostic systems, bus systems and identification systems, control systems and connection technology.
