Test thermocouple two aspect factors

We all know, the thermocouple he actually is a kind of temperature sensing element, is also a kind of an instrument. He is composed of two different materials of a closed loop. , of course, also because material is different, so the electronic density had spread, so that he could have potential. So if we are testing HuiXin thermal instrumentation thermocouple which two problems we should pay attention to?

if both sides have a temperature, so he will be in the loop current, which is the thermoelectric emfs, and current will be larger and larger. We want to know what HuiXin thermal meter thermocouple he is actually an energy converter, he can take the heat energy into electrical energy. Thermocouple advantage also has a lot of, such as his test range is wide, performance is also very temperature, and high precision, he can also directly contact and test objects, not affected by the media.

he thermal response time also quickly, has high reliability and mechanical strength is also very good, long service life, but also because their nature is not the same as the temperature difference will occur. If we put the two different conductor or semiconductor to connect, that this is a closed loop, but is by the temperature difference in the two conductors. He will have a thermoelectric effect, thermocouple he is used to conduct the reaction.
