[0002] Thermocouples are temperature measurement devices widely used in industry and scientific research. They measure temperature based on the thermoelectric effect between two dissimilar metals. The core principle of thermocouples is the Seebeck effect, which describes the electromotive force generated when a temperature difference exists at the junction of two conductors of dissimilar materials. Thermocouples are widely used due to their simple structure, wide measurement range, fast response, and excellent stability.

[0003] The multi-point high-temperature thermocouple in the existing technology cannot cool the inside of the protective sleeve. The tube wall will expand at high temperature, which is prone to produce tiny pores, causing corrosive gas media to penetrate into the inner wall of the thermocouple inner sleeve, causing temperature drift, and finally leading to the breakage of the thermocouple wire and a shortened service life. In addition, when one of the detection heads of the existing multi-point high-temperature thermocouple is damaged, it is impossible to replace it separately. The entire high-temperature thermocouple needs to be replaced, which wastes resources and is not convenient to use. Utility Model Content
