本文考察了用于13～273K的5支双引线100Ω的工业铂电阻温度计的稳定性。静态稳定性是将温度计置于室温3个月后检查的,动态稳定性是将温度计从室温到液氦温度重复进行5次和50次热循环后测得的。有4支温度计经5次热循环后,动态不稳定性在273K时小于0.3K,在13K时小于0.15K。仅1支温度计显示的动态不稳定性在两个温度点小于0.05K。所有的5支温度计的静态不稳定性比动态不稳定性低许多,可以忽略不计。 This article examines the stability of a 5-lead, dual-lead 100Ω industrial platinum resistance thermometer for 13-27K. Static stability is checked by placing the thermometer 3 months at room temperature. Dynamic stability is measured after the thermometer has been repeatedly subjected to 5 and 50 thermal cycles from room temperature to liquid helium temperature. 4 thermometers after 5 thermal cycles, the dynamic instability at 273K less than 0.3K, less than 0.15K at 13K. Only one thermometer shows less than 0.05K of dynamic instability at both temperatures. The static instability of all five thermometers is much lower than the dynamic instability and can be neglected.
