真空环境不仅会导致热电偶等温度传感器表面材料解吸,而且其传热机理也与常压不同,因此采用常压下校准和溯源的温度传感器测量真空环境下气体温度存在诸多不确定性问题. 为此,本文利用可调谐二极管激光吸收光谱技术(TDLAS)测量真空环境下气体温度,探索TDLAS温度测量技术在真空环境下的应用前景. 在模拟热真空实验过程中,首先将真空气室浸没于恒温槽中,然后利用TDLAS测量真空气室中气体温度,同时利用一等标准铂电阻测量恒温槽的温度. 试验结果表明:TDLAS和一等标准铂电阻测量得到的气体温度和恒温槽温度具有高度的一致性,两者之间的误差在恒温槽温度稳定时不超过0.2℃.

Measuring the temperature in vacuum environment is more complex than in atmospheric environment. For example, high vacuum will cause the thermocouple sensor surface desorption, and the mechanism of heat transfer is also different. Therefore, there are some uncertainties if the thermocouple is used to measure the gas temperature in vacuum condition. In the present paper, tunable diode laser absorption spectroscopy (TDLAS) is employed to measure the gas temperature and also explore the application prospect of TDLAS temperature measurement technology in vacuum environment. During the thermal vacuum experiments, the vacuum gas cell is immersed in the thermostatic bath, and the gas temperature is determined by TDLAS. Meanwhile, a standard Pt-resistance is used to measure the thermostatic bath temperature. The results show that the temperatures of the gas and thermostatic bath are highly consistent with each other, and the difference between the two temperatures is less than 0.2 ℃ when the thermostatic bath is stable.-
