摘　　要：在气流式倾角传感器的研制过程中,环境温度对传感器性能有不可忽视的影响。根据气流式倾角传感器的敏感机理和流动相似律,设计了一种温度补偿电路,使环境温度与传感器内部热源温度之差保持不变,从而消除环境温度对传感器性能的影响。试验结果表明,这种方法能够实时地对气流式倾角传感器进行补偿,有效地消除了环境温度对气流式倾角传感器性能的影响。During the research and development of gas pendulum tilt sensor, it was found that the influence of environmental temperature on sensor property couldn＇t be neglected. According to the sensing mechanism of gas pendulum sensor and the fluid similarity, a temperature compensation circuit that made the differenee between environment temperature and inner of sensor keep invariable was designed, and eonsequently the influence of environmental temperature on tilt sensor property was eliminated. Experiment results showed that this method eould compensate for tilt sensor on real time and effectively eliminate the influence of environmental temperature on tilt sensor property.
