In the process of industrial production, temperature is one of the important parameters that need to be measured and controlled. In temperature measurement, the application of thermocouple is very extensive, it has many advantages, such as simple structure, convenient manufacture, wide measuring range, high precision, small inertia and easy remote transmission of output signal.
In addition, because the thermocouple is an active sensor, it is often used to measure the temperature of the gas or liquid in the stove, pipe and the surface temperature of the solid without the need for additional power supply and is very convenient to use.
