| Abstract: | It is very important to measure atmospheric presure in the performance test of engine. The property and the measurement precision of sensor on atmospheric presure was analysed. The absolute presure sensor of diffuse silicon was adopted as atmospheric presure measurement in the engine test. A method to solve temperature drift was developed. Automatic measurement of atmospheric presure was realized. |
