Torque measurement

Apparatus for torque measurement in a rotating shaft, comprising a coil for inducing a magnetic field in the surface of the shaft, and a core structure having four poles adjacent the shaft surface with a sensing coil associated with each pole. The sensors of a first pair of poles have their output s...

Beschreibung
Zusammenfassung:	Apparatus for torque measurement in a rotating shaft, comprising a coil for inducing a magnetic field in the surface of the shaft, and a core structure having four poles adjacent the shaft surface with a sensing coil associated with each pole. The sensors of a first pair of poles have their output signals added, and those of a second pair added and subtracted from the combined signal of the first pair to give an output signal representing torque in the shaft. The sensors may be coils, or Hall-effect devices.
