由该方法制造的带自补偿热偶真空规管已申请中国专利 国产热偶规管是我国目前应用最普遍的粗低真空测控传感器。国产热偶规管的对热稳定性与美国DV系列热堆规管相比存在着明显差距,其原因就在于规管中的热端接点和冷端接点的热学特性不一致。国产规管中冷端接点的热惯性比热端接点大得多,从而使冷端接点的温度响应比热接点慢得多。本文提出的改进方法能将国产规管冷端的热惯性降低到与热端接点相当的程度。采用本方法不仅能提高国产热偶规管的热稳定性,而且还不需要对原来所配的真空计作任何改动,故极易推广普及。 并在文末附录部分对“环境热辐射与安装方位对热偶规的影响”一文(《真空1990(1)51~54)的理论推导和结论提出质疑。
The self-compensating thermocouple vacuum gauge manufactured by the method has applied for the Chinese patent thermocouple gauge control, which is the most widely used rough low vacuum gauge sensor in our country at present. There is a clear gap between the thermal stability of domestically produced thermocouples and the regulation of the United States DV series of thermopiles because of the inconsistent thermal characteristics of the hot and cold terminations in regulation. The domestic regulation of the thermal inertia of the cold junction is much larger than that of the hot junction so that the temperature response of the cold junction is much slower than the hot junction. The improved method proposed in this paper can reduce the thermal inertia of the domestic regulated cold junction to a level comparable to that of the hot junction. The method not only can improve the thermal stability of domestic thermocouple regulation, but also does not need to make any changes to the originally equipped vacuum gauge, so it is easy to popularize. And in the appendix at the end of the article on the “environmental radiation and installation of azimuth thermocouple regulation” article ("vacuum 1990 (1) 51 ~ 54) the theoretical derivation and conclusion questioned.
