摘要： A system for electrically detecting different positions of a movable piston within a piston housing of a hydraulic system is provided. The system includes at least two electrically conductive pads mounted on the piston housing at different locations along the path of movement of the piston, an electrically conductive segment mounted on the piston housing along the path of movement of the piston adjacent the conductive pads, and an electrical coupler, such as a spring-loaded conductor, attached for movement with the piston to provide an electrical connection between each conductive pad and the conductive segment as the piston moves along within the piston housing. The system also includes an electronic control unit, which may be a microprocessor, coupled to each conductive pad and the conductive segment to detect electrical connection between each conductive pad and the conductive segment. Each electrical connection corresponds to a specific position of the piston.
