Abstract (en)
[origin: WO02082031A2] A sensor head (2) for an eddy current sensor (4) is radially directed at a shaft (1). The electrical conductivity of the shaft (1) changes corresponding to the torque placed on the shaft. Said change leads to a change in the coupling power in the eddy current sensor (4) which is recorded in an analytical circuit. It is thus possible to reliably determine the torque on the shaft (1) without extensive constructive changes to the shaft.
