| description | A sensor for a variable displacement pump is provided. The pump has a housing containing a swashplate that is adapted to rotate about an axis. The sensor includes a magnet connected to the swashplate to rotate with the swashplate. A semiconductor chip is disposed proximate the magnet and within the housing. A control is adapted to direct a current through the semiconductor chip and to determine the voltage across the semiconductor chip. The control is further adapted to determine the angle of the swashplate relative to the housing based on the determined voltage. |
