摘要
目前用量最大的廉金属热电偶是镍铬-镍硅热电偶(K型热电偶),为保证计量性能的准确可靠,采用双极法对其进行检定,用一等标准铂铑10-铂热电偶检定一支K型II级热电偶,检定点选取1000℃。文章重点介绍了该检定方法和示值误差的不确定度评定。
The current most widely used cheap metal thermocouple is chromel-silicel thermocouple（K type thermocouple）. In order to ensure the accuracy and reliability of the calculation, we use bipolar method for its verification. The first standard Pt-Rh 10-platinum thermocouple is used to verify a K type Class II thermocouple, and the verification point is 1000℃. This paper mainly introduces the uncertainty evaluation of this verification method and the indication error.
