本文概要地介绍了光明化工研究所研制的两种铂电阻温度计的结构与制作工艺和分度方法,初步探讨了麦基森法则的适用性。数据分析表明,应用两个定标点于20K～80K范围内可以得到±0.1K的准确度。
This article gives a brief introduction of the structure, manufacturing process and indexing method of two kinds of platinum resistance thermometers developed by Guangming Chemical Institute, and discusses the applicability of McKesson’s law. Data analysis shows that the accuracy of ± 0.1K can be obtained by using two calibration points in the range of 20K ~ 80K.
