ABSTRACT:
Two magnetic field generators are fixed symmetrically with respect to a shaft in a first plane perpendicular to the shaft, and two magnetic field detector units are fixed symmetrically with respect to the shaft, in a second plane parallel to, and axially offset with respect to, the first plane. The detector units deliver a signal proportional to the torque owing to the relative angular offset of the generators with respect to the detector units such that the plane median to the first plane and second plane passes through the point of maximum deflection of the shaft under a longitudinal flexion force.
