Product introduction :
The thermocouple is a common temperature measuring element in the temperature measuring instrument. It directly measures the temperature, converts the temperature signal into the thermoelectric electromotive force signal, and converts the temperature of the measured medium through the electrical instrument ( secondary instrument ). The shapes of various thermocouples are often very different due to needs, but their basic structures are roughly the same. They are usually composed of main parts such as thermal electrodes, insulation sleeve protection tubes and junction boxes. They are usually used in conjunction with display instruments, recording instruments and electronic regulators.
In the industrial production process, temperature is one of the important parameters to be measured and controlled. Thermocouple is widely used in temperature measurement. It has many advantages such as simple structure, convenient manufacture, wide measurement range, high
