摘要
对目前发动机试验采用的压力传感器校准方法存在的问题进行了分析,针对这些问题,提出了一种压力传感器自动静态现场校准方法,该方法能减少对于压力标准源精度的依赖以及检定循环次数并提高校准工作效率。
The problems existing in the available calibration methods of pressure sensors used in the rocket engine test are analyzed in this paper. In order to solve these problems, an automatic static calibration method of the linear pressure sensor is proposed. This method can improve the calibration efficiency of pressure sensors and make up for the weakness of the current calibration methods by re- ducing the dependence on the accuracy of the pressure standard source and cycle times of the calibration.
