摘要

Apparatus for determining angle of esteru00e7amento and torque of the esteru00e7amento for a column of esteru00e7amento and apparatus for determining the angular position of a shaft.Apparatus for determining the angular position of a shaft, such as a column of esteru00e7amento, includes a set of coil, a coil support, and a coupler element having an angular position of the coupler correlated with the angular position of the shaft.The set of coil includes a transmitter coil and at least one receiving coil, the coupler element modifies the inductive coupling between the transmitter coil and at least a coil receiver.A signal processing circuit D receives signals of the coil from a set of coil and determines the angular position using a signal receiver and a reference signal correlated with an axial displacement, and substantially independent of the angular position.The reference signal can be used for sensing to substantially eliminate own common mode factors and also to determine the number of revolutions of the shaft. A sensor of torque and angle combined additionally determines the angle of deformation of the torsion bar.
