An added mass (30) is fastened freely at the diaphragm center for raising the switching threshold of the tire pressure sensor (13) as a function of speed and is dimensioned in such a way that the switching threshold is raised by a desired pressure differential (.DELTA.p) relative to the switching threshold p.sub.o at standstill at a predetermined radius r of the diaphragm (21), a predetermined rotational radius R of the diaphragm (21) and a predetermined rotational speed v of the diaphragm (21). The required added mass (m) results from the equation m=f(.DELTA.p, r.sup.2, R, v.sup.2), advantageously m=(.pi./4)r.sup.2 {[R/v.sup.2 ].DELTA.p - p.a}k wherein p is the material density of the diaphragm, a is the diaphragm thickness and the factor k is between 1.1 and 1.5.

    摘要: A sensor is suggested for measuring physical dimensions as well as a method for balancing its measuring values, whereby an evaluation circuit is used for the calculation of the accurate measuring value. The sensor (10) is combined with a PROM (15) into a structural unit (19), whereby the correction values for the measuring signals of sensor (10) are stored in PROM (15). Sensor (10) and PROM (15) have at least one output (18) through which the measuring signals as well as the correcting data have to be transmitted to evaluation circuit (30).

    摘要: A tire pressure detector for motor vehicles which is to be fastened at the circumference of a wheel rim and comprises an oscillating circuit having coupling coil which cooperates with a stationary receiver coil. In order to increase the minimum air gap between the rotating coupling coil and the stationary receiver coil, the coupling coil, which rotates with the wheel rim, is arranged on a middle limb of a plate-shaped ferrite core. The magnetic coupling for the stationary receiver coil is improved by means of the shape of the ferrite core (23).

    摘要: Disclosed is an electromagnetic relay whose armature assembly is protected against jarring impacts. The armature assembly is tiltably supported in a recess stamped out in an end portion of the magnetic yoke of the relay. Lateral inner walls of the recess are formed at their free ends with shoulders for engaging a flat biasing spring of the armature assembly. At least one lateral portion of the magnetic yoke delimiting the recess is formed with a constricted region, for example with a cutout in a corner between an inner wall and the bottom wall of the recess. The constriction permits the bending of the lateral projection into an open condition in which the corresponding shoulder is out of the way during the insertion of the armature assembly into the recess. Upon the insertion, the lateral projection is bent toward the armature until the corresponding shoulder overlaps the armature edge.
