A digital torque sensor employing a torsion bar, a target wheel at each end thereof, and at least two magnetosensitive (galvanomagnetic) sensors, in the form of magnetosensitive arrays, one for each target wheel, respectively, to precisely determine the angle of twist of the torsion bar. The torque sensor also provides target wheel relative position, rotational speed and rotational direction, and is capable of self-compensation over wide temperature ranges and air gaps, including tilts, does not require tight assembly tolerances and has a theoretically infinite life due to its non-contact nature.
