DEVICE FOR MEASURING A RELATIVE RATATION SPEED AND / OR A RELATIVE ANGULAR POSITION BETWEEN TWO ROTATING ELEMENTS

摘要

Device for measuring a relative speed and / or a relative angular position between a first rotating element (2) and a second rotating element (3) comprising: means for generating a magnetic field rotating at a speed of magnetic rotation representative of a rotation speed of the first rotating element; - A sensor (5) rotatably mounted and adapted to produce from the rotating magnetic field a measurement signal representative of the relative speed of rotation and / or the relative angular position; - processing means (11) positioned on the static part and intended to acquire the measurement signal; first transmission means adapted to transmit the measurement signal to the processing means from the sensor.
