Abstract
A measuring device for determining a torque of a rotating mechanical part includes a torsion element formed as a spoke wheel with at least one radially extending bending rod, a rigid part, and at least one spoke, and a measuring pickup having a measuring element connected with the rigid part, and another measuring element connected with the one spoke. Each of the measuring elements has a disc having a layer of an electroconductive non-magnetic material and a plurality of uniformly spaced regions of an electrically non-conductive material. The measuring device further includes at least one coil which changes impedance in accordance with a relative position of the measuring elements which relative position changes dependent on bending of the bending rod.
