Abstract: A torque sensor has a generator whose output signal is a function of a torque, a second signal generator, whose output signal changes in an opposite direction as a function of the torque, and an evaluation device which has a summing means which is connected to the two signal generators. For this purpose, connected to an integrator whose output is connected to a first input of a comparator whose second input is connected to the output of the comparator reset input of the integrator output of the torque sensor.

Abstract: A torque sensor has a first signal generator whose output signal changes as a function of a torque, a second signal generator whose output signal changes in the opposite direction as a function of the torque, and a circuit which has a difference-forming unit and a summing device. The output signal of each signal generator passes through an amplifier whose gain is controlled and identical for both output signals and the amplified output signals are present on the difference-forming unit and on the summing device the output of the summing device being connected to a controller which controls the gain.
