Abstract
An angular displacement sensor for determining the location of a rotating element such as a power clamp, fixedly attached to the power clamp adjacent the clamp arm. Specifically, the angular displacement sensor includes a rotating portion within a stationary housing, the rotating portion being directly connected to the axle that attaches the clamp arm to the connecting rods driven by the piston. By sensing the position of the rotating portion of the angular displacement sensor, which is directly connected to the axle and thereby rotates in direct proportion to the movement of the clamp arm, the sensor may easily determine the position of the clamp arm.
