摘要

The invention relates to a sensor device for inductive speed measurement of longitudinally mobile elements, having at least one measuring coil (4) and one permanent magnet (8) co-operating with said coil. The permanent magnet (8) co-operates with the element (or each element) that is to be detected, and is mounted so as to be mobile in the stationary measuring coil (4). There is also a compensating coil (6) which, owing to its spatial position, is also subjected, to a defined degree, to optionally occurring magnetic leakage fields.
