Abstract

A position sensor for a part submitted to reciprocal action due to rotation uses magnetic circuits to eliminate need for direct contact. This over comes difficulties of discontinuities obtained when potentiometer detectors are employed. A permanent magnet (6) is fixed to an operating handle (7) through an arm (8) connected to a shaft (9). The magnet and shaft have the same axis of rotation (10) perpendicular to the plane of a magnetic frame comprising two magnetic plates (1, 2) attached (3, 4) to a magnetic circuit (5). A winding on this circuit is connected to an alternating current supply (13) and transformer winding (15). Variations of magnetic flux strength due to position of the permanent magnet affect inductance of the magnetic circuit winding (12) to affect rectified (19) current in a resistor (18) at the transformer output.
