Abstract
A steering column differential angle position sensor includes an upper flux shutter and a lower flux shutter, both of which form a plurality of similarly shaped openings. Receiver and transmitter coils are coaxially aligned with the shutters. The transmitter coil provides a magnetic field around the shutters, with changes in the field being sensed by the receiver coil upon differential motion of the flux shutters. Using the output of the receiver coil, the torque on a steering column that is mechanically coupled to the shutters can be obtained.
