ABSTRACT:
A system for continuously providing direct readouts of horsepower and efficiency of a rotating shaft, which includes a husk assembly associated with the shaft and providing electrical signals proportional to shaft torque, a tachometer for providing electrical signals proportional to shaft rotational speed, electrical circuitry for electronically multiplying the torque signals by the RPM signals to determine shaft horsepower, and a dividing network for dividing the shaft horsepower signal into an electrical signal representing the rate of fuel consumption to provide a continuous indication of instantaneous system efficiency.
