| 摘 要： | 论述了温度对压力传感器输出灵敏度的影响，为了减小传感器输出的温度漂移，利用双惠斯登电桥方法进行补偿，在300～373K的温度范围内对传感器进行了测试。结果表明，采用双桥法补偿后，传感器输出的温度漂移可以降低70％以上。

| Abstract: | The effect of temperature on the output sensitivity of the piezo-resistive pressure sensor was discussed. In order to reduce the temperature drift of output for the piezo-resistive pressure sensor, the double Wheatstonebridge method is used to test the sensor with the temperature controlled at the range of 300-373 K. The results indicate that the temperature drift of the sensor output can be lowered by over 70%. |
