ABSTRACT:
An electromagnetic device for inductive position measurements for eliminating both the disadvantage of a limited measuring range and the disadvantage of superimposed interference voltages in the event of directional changes by providing a probe having a plurality of winding axes having coils with turn diameters which are greater, as the distance from the center of the probe increases. This creates the possibility of filling the entire probe volume with turns, and an almost complete independence from the direction of the probes relative to one another is shown for distance measures.
