Abstract
PURPOSE:To exactly detect the torque, even if the magnetic permeability is varied, by providing two sensor elements having a detecting coil, on arch-like magnetic cores, respectively. CONSTITUTION:When the torque of a right torsion or a left torsion is applied to an axis to be measured 2, a signal corresponding to the torque of a right torsion or a left torsion is obtained in an output terminal 14. Subsequently, when heat from a driving source 3 is transmitted to the axis to be measured 2 and its temperature is varied, magnitude of the magnetic permeability of a place 2b is varied. As a result, both magnetic fluxes PHIa, PHIb passing through each magnetic core of each sensor element 6a, 6b are varied in accordance with the magnetic permeability, and an output signal value of each coil in each sensor element 6a, 6b is fluctuated. In such a way, an exact torque corresponding signal which is not influenced by a temperature change can be obtained in the output terminal 14, and even if the magnetic permeability is varied, the torque can be detected exactly.
