Inductive sensor for speed, rotational direction and position measurements in the high temperature range

An inductive sensor with coils arranged in layers on a flat circuit-carrier,

• wherein the flat circuit-carrier has a surface at top and lateral faces which form a probe onto which a conductive material is applied by metallization, and
• the conductive material is interrupted along a helical path, on the lateral faces, so that a coil is formed whose helical path runs over all the lateral faces of the probe.

An inductive sensor comprising:

• a flat circuit carrier with a plurality of probes being aligned along an edge of the circuit carrier,
• each probe comprises three or four metallized lateral faces and a top face, and
• each of the three or four metallized faces comprising channels which are cut therein to form a helical coil that spans a length of all the lateral faces.
