Thermocouple is a temperature sensing element, is a kind of instrument.

It directly measuring the temperature and turn signal thermocouple thermoelectric emf signal, through electric instrument (secondary instrument) is transformed into the temperature of the measured medium.

Thermocouple temperature measurement is the basic principle of two kinds of different ingredients of closed loop conductor material composition, when when there is a temperature gradient at both ends, loop will have an electric current passes through, the existed between the electromotive force on both ends - thermoelectric emf, this is the so-called seebeck effect.

Two different components of homogeneous conductor electrode as heat, the temperature is higher for work at the end of the end, one end of the low temperature as the free end, usually free end under a constant temperature.

According to the thermoelectric emf as a function of temperature, the thermocouple indexing table;

Indexing table is free end temperature at 0 ℃, under the condition of different thermocouples with different indexing table.

Basic principle of thermocouple temperature measurement: the two different material A conductor or semi-conductor A and B welding together, form A closed loop.

ature difference between 1 and 2, occurs between the electromotive force, thus forming the size of A current in the circuit, this kind of phenomenon called the thermoelectric effect.

Thermocouple is in using this effect to work.
