1. A position sensor comprising an exciting coil having its convolutions disposed in a first plane, anda sensing coil having its convolutions disposed in a plane intersecting the first plane, the sensing coil having corresponding portions thereof disposed substantially symmetrically relative to a first portion of the exciting coil in the first plane in mutually inductive relation to said exciting coil portion, andmeans for mounting said exciting and sensing coil portions to be relatively movable with respect to mutual inductance modifying means on an object whose position is to be monitored so that the mutual inductances between said respective, corresponding sensing coil portions and said first exciting coil portion are modified relative to each other as the object is moved so that, when the exciting coil is driven, the sensing coil provides a signal representative of the position of the object relative to said exciting and sensing coil portions.
