Abstract:
Apparatus for measuring the horsepower transmitted by the drive shaft of an automotive vehicle, by determining the torque on the shaft through the measurement of the resistance of an included strain gauge, yet without the need for a power supply, such as a battery, being on the rotating shaft itself, and by employing a capacitive coupling to transmit power and signal to and from the drive shaft and fixed part of the vehicle.
