摘要：
The device for the contactless measurement of the rotational speed of a first part which rotates during operation and which is arranged inside a second part that either does not rotate or rotates at a rotational speed that is independent of the rotational speed of the first part, has an arrangement which generates a magnetic field and a magnetic field detector, wherein the arrangement which generates the magnetic field has a magnet ring (4) integrated in the inner part (1) and wherein the magnetic field detector is a Hall-effect sensor (3) situated in a housing (6) that surrounds both parts: the second part (2) consists of a non-magnetizable material.
