铠装热电偶广泛用于工业生产,做好铠装热电偶的量传工作有利于保障工业生产的顺利进行。本实验室在一次校准工作中发现,不同标准装置测量同一支热电偶的测量结果差异明显,接着设计多种实验,希望能找出存在差异的原因,有利于本实验室开展准确可靠的校准工作。一、出现差异JJF1262-2010《铠装热电偶校准规范》适用于测温范围-40℃~1100℃的铠装廉金属热电偶的校准。规范要求测量300℃以下的时候,采用二等标准铂电阻
Armored thermocouple is widely used in industrial production, good quantity of armored thermocouple work is conducive to the protection of industrial production smoothly. The laboratory found in a calibration work, different standard devices measure the same thermocouple measurement results were significantly different, and then design a variety of experiments, hoping to find out the reasons for the difference, is conducive to the laboratory to carry out accurate and reliable calibration . First, there is a difference JJF1262-2010 “armored thermocouple calibration specification” Suitable for temperature range -40 ℃ ~ 1100 ℃ armored metal thermocouple calibration. Specifications require measurement below 300 ℃, the use of second-class standard platinum resistance
