    • 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.
    • 传感器装置具有石英音叉和分布电路,该分析电路布置在公共壳体内的公共板上。 石英音叉在公共壳体内具有自己的第二个壳体,用于将音叉与分析电路进行声学去耦。 第二壳体还具有用于平衡第二壳体和公共壳体的其余部分之间的压力和温度的开口。 通过电线连接到石英音叉的分析电路进行线性化,信号放大和消除对石英音叉发出的信号的环境影响。 由分析电路处理的信号通过公共壳体的电触点进一步传输到外部元件。 由于石英音叉和分析电路的物理接近性,两个元件之间的电连接引起的干扰最小化。 此外,由于音叉和分析电路暴露在相同的温度下,音叉的电信号中的温度相关波动可以被分析电路准确地反平衡。

    • An apparatus for determining a rotation rate has an oscillatory body 11 on which a plurality of electromechanical converters A, A′, B, B′, C, C′, D, D′ are mounted. At least a first converter A, A′ is caused to oscillate mechanically by an electric driver signal UF,O generated in a first circuit arrangement 12. Further, at least a second converter D, D′ is caused to oscillate mechanically by an electric damping signal UF, D generated in a second circuit arrangement 13. At least a third converter C, C′ emits an electric sensor damping signal US, D which corresponds to the oscillation of the body 11 in the location where the at least third converter D, D′ is mounted. The damping sensor signal US, D is fed back to the input of the second circuit arrangement 13. A voltage divider 31 is provided, by means of which the signal UF, D generated in the second circuit arrangement 13 can be reduced.
