Technical parameters / requirements

The inductive and therefore contactless measuring principle can be applied on all ferromagnetic shafts or parts with at least weak ferromagnetic properties. An application on non-ferromagnetic shafts (carbon-fiber shafts) can be realized by a thin sputtering layer of soft magnetic material on the surface of the measuring object.
