摘要： Position sensor (10′) and method for measuring the position of an object comprising, a sensing element and an oscillator (30) coupled to the sensing element such that an electromagnetic field is emitted from the sensing element. An output, arranged to provide a signal, varies in dependence upon a change in an electrical property of the oscillator (30). Change in object position relative to the sensing element alters the electrical property of the oscillator (30). Sensing element comprises at least one discontinuity arranged to perturb the signal at a predetermined object position. Alternatively, there is a temperature compensator in proximity to the sensing element and arranged to compensate the signal for changes in temperature.
