Abstract:
Apparatus for determining the position of a piston in a hydraulically or pneumatically operated actuator including a fixed position, rotatable shaft having a pair of attached pins, each pin off-set from the center of the shaft. The pins are positioned on either side of a drive ring located about the circumference of the piston. When the piston moves in either direction, one of the pair of pins will remain in contact with the drive ring and cause uni-directional rotation of the shaft. In order to detect piston position, a sensor is mounted to detect shaft rotation.
