Abstract
An optical torquemeter adapted to provide torque readings as accurate as 1-to-2 foot pounds over a torque range of the order of 1 to 2 thousand foot pounds. It converts a binary-type optical message to an electric signal in the form of variable-width pulses. The width of the electric pulses indicates both the magnitude and the direction of torque and the pulses are processed to provide an output representing torque.
