ABSTRACT:
A torsion bar type torque sensor system is provided with the following: an elastic member that receives a torque and converts the torque to a torsion displacement; a multipolar ring magnet in which N poles and S poles are circumferentially and alternately magnetized; a pair of magnetic yoke halves disposed coaxially with the ring magnet; and a magnetometric sensor that detects magnetic flux generated between the pair of the magnetic yoke halves. The magnetometric sensor is made of a semiconductor that integrates a semiconductor magnetometric sensor, a non-volatile memory, a computation circuit, and an output circuit. This structure provides a torque sensor system that has an excellent maintainability.
