Abstract
A torque sensor is provided with a pair of coils whose inductances vary in opposite directions in accordance with torque, and a differential amplifier circuit for differentially amplifying a pair of detection voltages induced by and received from the pair of coils so as to detect the torque by means of the output of the differential amplifier circuit. The torque sensor further includes a detection circuit using the detection voltage as an input to send out a detection signal when the input exceeds a predetermined upper limit value or becomes lower than a predetermined lower limit value, and a control circuit for controlling the differential amplifier circuit on receiving the detection signal so that the output of the differential amplifier circuit has a predetermined value outside a steady output range.
