- 为了准确测量液氧/煤油发动机试验过程中的液氧流量,在液氧主容器中设计、安装了铜-康铜热电偶传感器构成的分层温度测量装置。根据热电偶温度测量原理,分析参考端、接插件等因素对容器内液氧温度测量值的影响,提出改进措施,提高了容器液氧温度测量精度。
- Abstract:
- In order to measure the LO2 flow in the process of LO2/kerosene engine test accurately, a layered temperature measuring device composed of copper-constantan thermocouple sensors was designed and installed in the LO2 main container. According to the principle of thermocouple temperature measurement, the effects of reference junction, connectors and other factors on measured value of LO2 temperature within the container are analyzed, and some improvement measures are put forward. The measurement accuracy of LO2 temperature within container has been improved.
