Apparatus for monitoring operation of a drive shaft

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