通过实验对压力传感器的温度效应进行了研究。结果表明 ,当温度在低温范围内变化时 ,压力传感器的零点输出有较大的变化 ,但输出特性仍保持良好的线性 ;灵敏系数随温度的升高而减小。
The temperature effect of the pressure sensor is studied experimentally. The results show that when the temperature changes in the low temperature range, the zero output of the pressure sensor has a great change, but the output characteristics still maintain good linearity; the sensitivity coefficient decreases with the increase of the temperature.
