摘要
补偿导线对廉金属热电偶的校准结果影响很大,JJF 1637-2017《廉金属热电偶校准规范》中明确提出补偿导线必须作为廉金属热电偶校准过程中的配套设备之一,并有具体的技术要求。本文介绍了廉金属热电偶校准过程中补偿导线的用途、常见类型和选用方法,以及注意事项。
Compensation lead has great impact on calibration result of base metal thermocouples.JJF 1637 -2017 "Calibration Specification for Base Metal Thermocouples"clearly proposes that compensation lead must be one of supporting equipments during calibration of base metal thermocouples and has specific technology requirement.This thesis introduces use,common types,selecting method and matters needing attention of compensation lead during calibration of base metal thermocouples.
