摘　　要：热电偶是温度测量中最常用的传感器之一,被广泛地应用在工业测量中。而K型热电偶是最常见的一种,对它的的校准是采用比较法中的双极法。本文详细论述了用一等铂铑10-铂热电偶校准K型廉金属热电偶时不确定度评定的详细过程,对校准廉金属热电偶工作具有一定的指导意义。Thermocouple is one of the most commonly used sensors in temperature measurement,which is widely used in industrial measurement.K-type thermocouple is the most common one,and its calibration is based on the bipolar method of comparative method.This paper describes in detail the evaluation process of uncertainty in calibrating K-type Base Metal thermocouple with first-class platinum rhodium 10-platinum thermocouple,which has certain guiding significance for calibrating Base Metal thermocouple.
