ABSTRACT:
A method and apparatus is disclosed for nullifying electrical offsets present in an output signal from a torsion sensing device. The apparatus includes a detection circuit for outputting an electrical signal when a change between a no applied torque condition and an applied torque condition occurs in a member whose torsion is being monitored. A sample and hold circuit measures the output signal from the torsion sensing device, the sample and hold circuit being triggered in response to the detection circuit. A differencing circuit subtracts the output of the sample and hold circuit from a "zero torque" reference value and outputs an electrical signal having a value indicative of the difference therebetween. An offset compensating circuit is electrically connected to the output of the differencing circuit and to the torsion sensing device and outputs a modified torsion sensing signal having a value that varies as a function of the applied torque offset by the value of the output of the differencing circuit.
