Abstract:
A torque sensor comprising:a first signal generator, having an output signal that changes in a first direction as a function of a torque, a second signal generator, having output signal that changes in a second direction opposite to said first direction as a function of the torque, and an evaluation circuit which is comprised of a summing device having a first input connected to the first signal generator and a second input connected to the second signal generator, which provides an output summing the first and second inputs, wherein the first signal generator is connected to an integrator having output an connected to a first input of a comparator having second input an connected to the output of the summing device, the output of the comparator being connected to a reset input of the integrator and to a signal output from the torque sensor, wherein the integrator is reset at a frequency proportional to the torque.
