Description

Technical Field

[0001] This application relates to the field of armored thermocouples, and in particular to an assembly device for armored thermocouples. Background Technology

[0002] Armored thermocouples, as temperature measurement sensors, are typically used in conjunction with temperature transmitters, controllers, and display instruments to form process control systems. They are used to directly measure or control the temperature of fluids, steam, gases, and solid surfaces within the 0-1800℃ range during various production processes. Armored thermocouples offer many advantages, including flexibility, high pressure resistance, fast thermal response time, and durability. Like industrial assembly thermocouples, they are used as temperature measurement sensors, usually in conjunction with display instruments, recording instruments, and electronic controllers.

[0003] In the food, chemical, and rubber industries, processes such as melting, distillation, and concentration are carried out during production. All of these processes take place in reaction vessels and tanks, and strict temperature control is required. When armored thermocouples are used as temperature measurement sensors, they are usually fixed with clamps or straps, which are difficult to install and not stable enough. Furthermore, once fixed, they cannot be adjusted, making it impossible to detect the temperature of reactants at different depths. Utility Model Content
