Abstract: A sensor device for speed measurement on a wheel of a vehicle includes a sensor carrier with an integrated sensor to sense the rotation of a pole wheel that rotates along with the wheel. The sensor device has a clamping mechanism integrated into the sensor carrier by which the sensor carrier can be displaceably clamped into a holding opening in the region of the wheel and/or in any orientation with respect to rotations about the longitudinal axis of the sensor carrier. The sensor arrangement can be mounted with less effort and more cost-efficiently than with the current international standard of combining a clamping bush and subsequently mounted rod sensor. Spring-loaded clamps can be fastened as terminal blocks in longitudinal grooves in the sensor, and the spring-loaded elements thereof can protrude over the circumference of the sensor prior to mounting.

Abstract: Disclosed is a support (10) for a sensor element (11). The support (10) is for potting and manufacturing a rotational speed sensor. The support (10) comprises an at least partially hollow body for accommodating electric contacts and a potting compound. According to the invention, a cover (25) is provided for covering and filling a recess defined by the at least partially hollow body.

Abstract: A sensor device (12) to measure the speed of a wheel of a vehicle is disclosed. The sensor device (12) is assigned an identifier (28, 30, 32) which can be contactlessly read. The identifier (28, 30, 32) can be read by radio. A method for identifying the sensor device (12) and a vehicle including the sensor device (12) are also disclosed.

Abstract: A magnetoresistance sensor has a first magnetic layer that changes polarity in response to an external magnetic field and a second magnetic layer having a fixed magnetic polarity oriented in a reference direction. A varying voltage is applied to establish a varying magnetic bias field in the reference direction. An evaluation circuit calculates the difference between maximum and minimum resistance values established in response to the external magnetic field.

Abstract: A sensing system includes a conductor with a current flow path therethrough configured such that a current flowing through the conductor establishes an inhomogeneous magnetic field. A first pair of sensors is situated a first location having a first sensitivity, a second pair of sensors is situated at a second location having a second sensitivity lower than the first sensitivity. The first and second pairs of sensors are configured to measure the inhomogeneous magnetic field at their respective locations.

Abstract: A sensing system includes a conductor with a current flow path therethrough. A first location of the conductor defines a first cross-sectional area and a second location defines a second cross-sectional area, wherein a current flowing through the conductor establishes magnetic field lines having strengths that vary according the conductor cross-sectional area. A plurality of sensors include a first and second sensors situated proximate the first and second locations, respectively, and configured to measure the magnetic field lines at their respective locations.
