ABSTRACT:
There is provided an apparatus for measuring operating parameters of a rotating shaft, which apparatus includes an encoder module attached to a first end of the shaft, an elongate member having a first end attached to a second end of the shaft and extending along the shaft, and an encoder disk attached to a second end of the elongate member and operatively disposed in proximity to the encoder module, such that twisting of the shaft caused by torque applied thereto will cause relative angular displacement between the encoder module and the encoder disk. In a further aspect of the invention, there is provided an apparatus for measuring the rate of revolution of a shaft, which apparatus includes a hollow, cylindrical, inwardly facing race defined within the shaft, a freely rolling ferromagnetic ball disposed in the race, and a permanent magnet with a coil therearound fixedly disposed with respect to the shaft and disposed near the race such that proximity of the ball to the magnet and coil will change the amount of magnetic flux to which the coil is otherwise subjected, so that the coil will output a pulse of current each time the magnet passes the ball as the shaft rotates.
