A fastening assembly for a sensor assembly has a metal bush and a fastener. It is possible for the metal bush to be connected via the fastener to a vehicle body. The sensor assembly includes at least one sensor module and an associated sensor assembly. The metal bush has a sleeve as a single-point fixing and a plate as a carrier unit for a carrier plate on which the at least one sensor module is arranged. The sleeve is led through a central through-passage in the carrier plate.

An apparatus for determining a rotation rate has an oscillatory body on which a plurality of electromechanical converters A, A&prime;, B, B&prime;, C, C&prime;, D, D&prime; are mounted. At least a first converter A, A&prime; is caused to oscillate mechanically by an electric driver signal U generated in a first circuit arrangement . Further, at least a second converter D, D&prime; is caused to oscillate mechanically by an electric damping signal U generated in a second circuit arrangement . At least a third converter C, C&prime; emits an electric sensor damping signal U which corresponds to the oscillation of the body in the location where the at least third converter D, D&prime; is mounted. The damping sensor signal U is fed back to the input of the second circuit arrangement . A voltage divider is provided, by means of which the signal U generated in the second circuit arrangement can be reduced.

The sensor apparatus includes a sensor device having a control current (I.sub.H) flowing through it, a sensitivity and a temperature dependence of the control current characterized by a temperature coefficient, and a temperature compensating circuit for compensating temperature changes adversely effecting the sensitivity of the sensor device. The temperature compensating circuit includes a circuit portion which sets or adjusts the temperature coefficient of the control current(I.sub.H) according to changes in the temperature dependent internal resistance of the sensor device so that changes in negative temperature coefficients of other physical quantities determining the sensor sensitivity are compensated.

A sensor device has a quartz tuning fork and an analysis circuit arranged on a common board inside a common housing. The quartz tuning fork has its own, second housing within the common housing for acoustically decoupling the tuning fork from the analysis circuit. The second housing also has an opening for equalizing the pressure and temperature between the second housing and the rest of the common housing. The analysis circuit, which is connected via the electrical wires to the quartz tuning fork, performs linearization, signal amplification and elimination of environmental influences on the signals emitted by the quartz tuning fork. The signals processed by the analysis circuit are further transmitted via common housing's electrical contacts to external elements. Because of the physical proximity of the quartz tuning fork and the analysis circuit, interference attributable to electrical connections between the two elements is minimized. Furthermore, because the tuning fork and the analysis circuit are exposed to the same temperature, temperature-related fluctuations in the electrical signals of the tuning fork may be accurately counter-balanced by the analysis circuit.
