Abstract
Arrangement for inductive speed detection in which two planar coils are arranged offset at a given distance from a so-called pulse wheel and in the rotational direction of the pulse wheel, and are each part of an oscillator, the oscillator frequency of which is evaluated.

Arrangement for inductive speed and rotational direction detection in which two planar coils (1, 2)
- are arranged offset at a given distance from a so-called pulse wheel and
- in the rotational direction of said pulse wheel,
- and are each part of an oscillator, the oscillator frequency of which is evaluated.
Arrangement for inductive speed and rotational direction detection in which said one planar coil (1)
- is arranged at a distance from a so-called pulse wheel and
- said pulse wheel is coded and
- said planar coil (1) is part of an oscillator, the oscillator frequency of which is evaluated.
