Firstly, the situation of AMS 2750G standard is briefly introduced, as well as the status of research and application of the new concept of calibration of temperature measurement system, i.e., online calibration. The concepts of offline calibration, online calibration, and the relationship between the two, as well as the development and application of portable online calibrators and thermocouples with calibration holes series are introduced. Then, the development and application of refractory metal thermocouple that tungsten rhenium thermocouple is elaborated in detail, including the characteristics and classification of tungsten rhenium thermocouple, the international leading anti-oxidation technology, and the performance of tungsten rhenium thermocouple at home and abroad is compared. Finally, the research and application of localization of imported temperature sensors are summarized, including the localization research of special thermocouples for multi-purpose furnace and carburizing furnace, thermocouples with calibrated holes, and special thermocouples for glow ion nitriding furnace, etc., as well as the work of replacing precious metal thermocouples with inexpensive metal and refractory metal thermocouples. This research will provide new ideas for practitioners in the high-temperature measurement industry to select suitable temperature sensors.
