Properties of High Temperature Thermocouples

Thermocouple is a kind of temperature measuring instrument. Its maximum temperature can be detected to 1800 degrees. Today, I will share with you the properties of high temperature thermocouples. Thermocouple is a temperature sensing element and instrument that can directly measure temperature, convert temperature signal into thermoelectromotive force signal, and then convert it into the temperature of the measured medium through electrical instruments. Although the shapes of various thermocouples are often different due to their needs, their basic structures are roughly the same. Use with the regulator. The main attributes of thermocouples are: simple structure, convenient manufacture, wide measurement range, high precision, small inertia and easy remote transmission of output signals. Not only that, in terms of performance, thermocouples can also show many advantages. The compression spring type temperature sensing element provides it with good shock resistance and ensures the stability of the installation. Thermocouples measure temperature with minimal error. When a third metal material is connected to the thermocouple loop, as long as the temperature of the two junctions of the material is the same, the thermoelectric potential generated by the thermocouple will remain unchanged, that is, it will not be affected by the third metal being connected to the loop. Therefore, when measuring the temperature of the thermocouple, the measuring instrument can be connected, and the temperature of the measured medium can be known after measuring the thermoelectromotive force. Thermocouples have high mechanical strength, good pressure resistance, and high temperature resistance up to 2800 degrees, so they have a long service life. These advantages are relatively advanced in domestic products. The above are the properties of high temperature thermocouples, I hope to be more helpful to users who understand thermocouples!
