Device for measuring revolution rate has revolution rate sensor arranged between two rotatable elements with two sensor elements facing rotatable element markings in axial direction

摘要

The device has a revolution rate sensor arranged between two rotatable elements (3,4) with two sensor elements (13,14) facing the markings in the axial direction. The markings and the sensor elements are arranged on a straight line. The sensor elements are magnetic field dependent and the sensor has a permanent magnet (12) between them.
