Description

Technical Field

[0001] The utility model relates to the technical field of temperature measurement modules, in particular to a fixing device for a thermocouple temperature measurement module. Background Art

[0002] Thermocouple temperature measurement module is one of the important ways to collect temperature signals for heating furnaces in large steel plants. Thermocouple is a temperature sensing element and an instrument. It directly measures temperature and converts temperature signals into thermoelectric potential signals, which are then converted into the temperature of the measured medium through the signal acquisition system (i.e. the above-mentioned temperature measurement module). The basic principle of thermocouple temperature measurement is that two conductors of different materials form a closed loop. When there is a temperature gradient at both ends, current will flow through the loop. At this time, there is an electromotive force between the two ends - thermoelectric potential. The thermoelectric potential signal is obtained through the signal acquisition system, and then the relationship between temperature and thermoelectric potential is compared to obtain the temperature signal.

[0003] Generally, thermocouples are divided into K-type, J-type, T-type, E-type, etc. according to different materials, and there are standard thermocouple graduation tables. Different thermocouples have different graduation tables. Therefore, when thermocouples are used for temperature measurement, they can be connected to measuring instruments, and after measuring the thermoelectric potential, the temperature of the measured medium can be known.

[0004] Thermocouples are very sensitive to temperature changes and have a fast response time. They can quickly sense temperature changes and output corresponding electrical signals, so they are very suitable for situations where real-time monitoring and control of temperature are required. Thermocouples also have high durability and corrosion resistance. They can work under various harsh environmental conditions, especially for high temperature, high humidity and corrosive gas environments in steel plants. Although thermocouples are suitable for the harsh environment of steel plants, they are extremely unfriendly to the use of thermocouple temperature measurement modules for high-precision precision instruments. The temperature measurement module is composed of a series of electronic devices such as resistors and capacitors, and cannot withstand external forces, which will greatly limit the choice of the temperature measurement module for the application environment.

[0005] However, considering the economic benefits, the use of thermocouple temperature measurement modules is still common, so it is particularly important to design a fixing and protection device for the thermocouple temperature measurement module. Summary of the invention
