ABSTRACT:
The sensor described in the specification and which compares the rotary wheel deceleration with the linear vehicle deceleration, comprises a mass which is subject to both decelerations and whose movement is checked by an electrical sensing means rotating with the shaft. This sensing means provides data signals in the case of an excessive difference between the two decelerations without the need of a mechanical contact between the sensing means and the mass. The description further shows sensors which measure completely non-contacting and which transmit the data signals without the use of slip rings. These sensors can also measure the angular wheel deceleration and simultaneously the transversal deceleration of a vehicle.
