发动机点火装置中的气压压力及气流压力校准

Calibration of Gas Pressure and Gas Flow Pressure in Igniter of Engine

以压力传感器与数显仪表的测量原理为基础,简述了发动机点火装置中的气压压力及气流压力校准装置及校准方法,给出了测量不确定度的评定。

Based on the principle of the pressure sensor and digital display instrument, this paper briefly introduces the calibration instrument and calibration method of gas pressure and gas flow pressure in the igniter of a engine. The evaluation of the uncertainty of measurement has been given.
