本文介绍了一种石英音叉温度传感器的设计新方法。该传感器设计了一个新的切割ZYtw（115°/15°），它被证明是最好的工作在弯曲振动模式。从理论上分析了提高信噪比和减小传感器等效电阻的途径。已经确定了一种制造方法来形成和调整精确的频率，这可以提高灵敏度并降低非线性。
This paper describes a new method designed for a quartz tuning‐fork temperature sensor. This sensor is designed with a new cut ZYtw(115°/15°) and it is shown that this worked best in flexural vibration mode. The way for raising signal to noise ratio and reducing equivalent resistor of the sensor were analyzed in theory. A manufacturing method has been determined to form and adjust the precise frequency, which could improve sensitivity and reduce non‐linearity.
