The objective of this research was to investigate the possibility of the temperature compensation for the surface acoustic wave (SAW) yarn tension sensor. The motivation for this work was prompted by the oscillation frequency of the SAW yarn tension sensor varying with the temperature. In this paper, we deduce the functional relationship between the temperature variation and the oscillation frequency shift caused by the temperature. This functional relationship and the temperature sensor are used to get the oscillation frequency shift caused by the temperature, so that we can use the oscillation frequency shift caused by the temperature to implement the temperature compensation of the SAW yarn tension sensor. In this paper, we also get the relative error of the temperature compensation. The theoretical and experimental results confirm that this temperature compensation method can implement the temperature compensation of the SAW yarn tension sensor.
本研究的目的是探讨表面声波（SAW）纱线张力传感器温度补偿的可能性。这项工作的动机是由SAW纱线张力传感器的振荡频率随温度变化而引发的。在本文中，我们推导了温度变化与温度引起的振荡频率偏移之间的函数关系。利用这种函数关系和温度传感器来获取温度引起的振荡频率偏移，从而能够利用温度引起的振荡频率偏移来实现SAW纱线张力传感器的温度补偿。在本文中，我们还得到了温度补偿的相对误差。理论和实验结果证实，这种温度补偿方法能够实现SAW纱线张力传感器的温度补偿。
