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.
