Abstract
A magnetic angle sensor system for determining a shaft angle for one or more pivoting or rotating shaft means. The or each of said shaft means is provided with means adapted to generate a magnetic field, such that means can be energised in turn to induce a magnetic field in a detector. In a first step the sensor arrangement measures the background field in the absence of any current in the wire or solenoid, such that the angle of the shaft means can be determined from the magnetic field in the solenoid and the background field. The invention concerns the use of an evoked response field whether alternating or steady whereby the angle is determined by the difference in field when the evoking magnetic stimulus is present from when it is absent.
