The sensor for filter monitoring is installed on the suction side as close as possible to the pump. The pressure measured allows conclusions to be drawn about the condition of the filter element and the suction line in general. This allows detecting pending maintenance or cleaning of the filter as well as a closed supply line. A reliable liquid supply of the micro annular gear pumps, especially in production plants (24/7 operation) is thus guaranteed.

The implementation of the sensor is very easy. It can be attached directly to T-filters or integrated into the suction line by means of a separate mounting block. Later upgrades are possible.

There are several sensor versions available. In addition to the simple pressure sensor with analog output, pressure switches with digital display, optical LED displays and/or configurable output signals are available. Pressure switches can give feedback when previously defined pressure thresholds are reached. The pressure switches can be configured to meet specific customer requirements via IO-Link interface.
