Torque meter means

Abstract From the Canadian patent

A torque meter which measures the torque of a rotating shaft includes at least two sensors. Portions of each sensor are fixed to the shaft. The sensors provide shaft pulse signals at the same frequency but having a phase difference corresponding to the torque experienced by the shaft. A clock provides clock pulses. A circuit connected to the sensors and to the clock provides first groups of pulses in accordance with the shaft pulse signals so that the number of pulses in each group of the first group of pulses corresponds to the torque experienced by the shaft at a constant speed. A first counting network counts the pulses from the circuit. Another circuit connected to the clock provides …
