Claim:
1. A sensor assembly for use with a clutch assembly having a plurality of clutch plates and pressure plates, a housing positioned adjacent the plurality of clutch plates and pressure plates, at least one pair of pistons connected to the clutch plates and the pressure plates, the pistons movable within the housing, the sensor assembly comprising: a magnet connected to each of said pistons; a pair of magnetic sensors in communication with each of said magnets, said sensors being further in communication with an electrical control unit, a shield disposed between said pair of sensors for blocking magnetic fields between said sensors, said sensors operable to measure changes in magnetic fields as the pistons are caused to move in response to movement of the clutch plates and the pressure plates, the electronic control unit receiving an output signal from said sensors for determining the linear distance traveled of the clutch plates and pressure plates.
