Thermocouples are widely used in industry, but a commonly encountered difficulty is the thermoelectric drift which causes an unknown change to the thermovoltage over time. A comprehensive survey of the published information on drift rates for Types B, C, D, K, N, R, S, Au/Pt, and Pt/Pd thermocouples is presented. The data that are available for thermocouple drift rates are reviewed for each major thermocouple type, and any large gaps in the reported data are stated. The effects of different parameters on the drift rate are summarized, with a particular focus on what happens at different temperatures. The effects of temperature, thermoelement diameter, sheath and/or insulation type, atmosphere, and thermocycling on the drift rate are considered (where data are available). This will allow users to assess the likely magnitude of the drift rate of different thermocouples for a given application.

热电偶在工业中被广泛使用，但通常遇到的困难是热电漂移，它会导致热电压随时间发生未知变化。对已发布的 B、C、D、K、N、R、S、Au/Pt 和 Pt/Pd 热电偶的漂移率信息进行了全面调查。对每种主要热电偶类型的热电偶漂移率可用数据进行了审查，并说明了报告数据中的任何大差距。总结了不同参数对漂移率的影响，特别关注在不同温度下会发生什么。考虑了温度、热电偶直径、护套和/或绝缘类型、气氛和热循环对漂移率的影响（如果有数据）。
