To find the basis of a thermocouple for temperature measurement

In fact, a lot of friends is no stranger to thermocouple, it should be said, but if you said this thermocouple concrete is how to do the work but don't know where to start. Let below small make up from the light into a deep to tell you about those things about the thermocouple. In our life, we often use thermocouple to measure temperature, the friend is going to ask, why do we use thermocouple? , of course, this is by thermocouple his advantage by the people's trust, is simply his performance is more stable than that of the other devices to come, not only that, his composition is simple and dynamic response is better. He can let us better for automatic and centralized control. The thermocouple is the temperature measured by what? His measure of temperature is the same thermal reaction, he can put the two different conductor and semiconductor constitute a closed loop, so that when the temperature of the contact points of the two if not consistent, so it is good to have thermoelectric potential, this is called thermoelectric reaction. Thermocouple and thermal resistance can be used to measure temperature, though they said their purposes are the same but on the principle and characteristics are distinct. At the same time we also need to know, thermocouple his signals are electrical signals, but when to transfer his conductor is special. If we use the thermocouple is not the same as that we'll have to be very careful, so we used wire is different also, so that we can let it in and thermocouple can carry on the isolation and the power to connect, then yes the temperature of the measurement more accurate. If you want more skilled to use thermocouple measurement, that we have to clear his wire type, he has two types is a compensation of a kind is extended type, the former in and thermocouple to connect when he is simple and clear, usually, we are also in the quality of a material of copper and nickel alloy material.
