Abstract
A position sensor for determining a set position thereof is disclosed. The sensor comprises a time-varying magnetic field generator. A movable electrically conductive element is positioned such that the time-varying magnetic field generates eddy currents therein. At least one pick-up is provided for generating a signal in response to the time-varying magnetic field. Movement of the conductive element relative to the pick-up alters the magnetic coupling between the magnetic field generator and the pick-up allowing the set position to be determined unambiguously.
