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.
