Title: INDUCTIVE SENSOR FOR ROTATIONAL SPEED DETERMINATION WITH INTEGRATED TEMPERATURE MEASUREMENT
Abstract:
The invention relates to the use of an inductive signal generator (1), for recording the position, path, angular position, or rotational speed of a moving element, for also generating a signal for the temperature of one or more components (16, 26) arranged near the signal generator. An economical functional rationalisation in a single component is thus achieved. The sensor can display the temperature of a wheel bearing and/or the brakes. Brake overheating or bearing damage can be determined, by means of comparing the temperature on differing wheels.
