This hydraulic filter clogging sensor is mounted in the pump cover of the tractor's hydraulic system. It monitors the pressure differential across the filter element and signals when the element is obstructed. A clogged filter forces fluid through the bypass valve, which sends unfiltered oil downstream and can damage pump components. The sensor provides a direct electrical signal to the operator's cab, allowing for timely filter replacement before system damage occurs. As an original AGCO component, the sensor's electrical resistance curve and thread form match the housing's calibration, ensuring the warning threshold is set correctly for the host machine's hydraulic circuit.
