Abstract:
1. A configuration of a pair of inductor coils (A, B) in a local measuring range (M) and in a nominal distance of an eddy current damping part, a) whereby the pair of inductor coils (A, B), as rectangular coils (A, B), overlap within the measuring range (M) and the overlapping range forms the measuring range (M), b) whereby the pair of inductor coils (A, B) have an overhang of the coil length (L), in each case at one end of the measuring range (M), c) whereby the eddy current damping part, relative to the pair of coils (A, B), is shifting and the eddy current damping part at least partially covers both of the pair of coils (A, B), d) and the pair of inductor coils (A, B), with a measuring oscillator, each having a linear characteristic curve of the oscillator frequency (f) as a function of the location (position s or angle α), and e) these linear characteristic curves each have, largely independent from interferences, meaning a variation of the nominal distance, from tilting in the direction of measurement, and changes of the temperature, having a virtual, meaning outside of the measuring range (M), point of rotation (A
