一、前言在我国广泛应用廉金属热电偶。由于该热电偶线径粗细不等,在检定时,参考端的处理很不方便。目前检定热电偶时,参考端的处理方法较多,例如:有将参考端直接置于冰点器内或室温中;也有在热电偶端头接补偿导线后,其导线另一端置于冰点器内或室温中;此外也有接用电子式冷端补偿器等。本文探讨这些不同参考端处理方法对检定结果的影响。
First, the preface Widely used in China low-metal thermocouple. Due to the thermocouple wire thickness ranging from the test, the reference end of the treatment is very convenient. The current test thermocouple, the reference end of the treatment methods are more, for example: the reference end is placed directly in the freezing point or at room temperature; there are thermocouple end compensation wire, the other end of the wire placed in the freezing point or Room temperature; also have access to electronic cold junction compensator. This article explores the impact of these different reference end treatments on assay results.
