Filter monitor

The type PMP differential pressure sensors are designed for monitoring filters for air and other gases. The compact microprocessor controlled units are housed in a robust plastic casing with an enclosure class of IP65.

Two hose connections allow easy connection to the process before and after the filter. The measuring range runs from 0 to 50 mbar. The measuring process that is used registers even tiny pressure differences with great accuracy. Meanwhile, the sensor is safe against overloads up to 750 mbar.

One 4-20 mA analog output and two relay outputs are available and the easy-to-operate electronics offer all necessary settings. The relays, their time delay, the hysteresis as well as the analog signal are freely programmable. A 4-digit LED display provides direct information on the spot.

With the aid of the type PMP differential pressure sensors, the cleaning or replacement of filters can be carried out dependent on the degree of contamination and precisely at the right time. Energy losses due to clogged or used filters can be easily and inexpensively avoided.
