ABSTRACT:
A non-contacting shaft horsepower measurement system in which a torque indicating signal is obtained from the phase shift between a pair of signals derived from two sensors sensing the passage of a torque responsive toothed wheel and a reference toothed wheel spaced on the shaft, this torque signal being then multiplied by a speed signal derived from a third sensor thereby developing a signal proportional to instantaneous horsepower.
