热电偶测量端位置的准确定位对于热电偶的校准和使用有着重要影响,特别对于铠装贵金属热电偶来说,由于无法通过肉眼准确识别保护管内部热电偶测量端的位置,因此在热电偶检定和使用过程中一般将其外保护管顶部作为测量端所在位置。然而通过现场试验发现,铠装贵金属热电偶测量端一般并不位于保护管顶部,本文提供了一种准确定位铠装贵金属热电偶测量端的方法。
熱電偶測量耑位置的準確定位對于熱電偶的校準和使用有著重要影響,特彆對于鎧裝貴金屬熱電偶來說,由于無法通過肉眼準確識彆保護管內部熱電偶測量耑的位置,因此在熱電偶檢定和使用過程中一般將其外保護管頂部作為測量耑所在位置。然而通過現場試驗髮現,鎧裝貴金屬熱電偶測量耑一般併不位于保護管頂部,本文提供瞭一種準確定位鎧裝貴金屬熱電偶測量耑的方法。

Accurate positioning of measuring ends of thermocouples has an important influence on the calibration and use of thermocouples, especially for armored noble metal thermocouples. It is impossible to accurately identify the position of thermocouple measuring ends inside protec-tion tubes by visual inspection, and therefore the top of protection tubes is chosen as the position for measuring ends in the calibration and use processes of thermocouples. However, through field test, the measuring ends of armored noble metal thermocouples are not located at the top of protection tubes. This paper provides a method for accurate positioning of armored noble metal thermocouple measuring ends.
