What are the characteristics of the armored thermocouple? Armoured thermocouple temperature measurement is used in the temperature of the common objects, kiss his important characteristic is measured area wide, solid, armoured thermocouple function compare with easy structure, static echo is good, can far eastone 4 - more 20 ma electrical signals to facilitate active control and centralized control.

the thermocouple temperature measurement principle is based on thermoelectric effect. Two different conductors or semiconductor cohesion into closed loops, when the temperature of the two contact in not together, will happen loop thermoelectric potential, this picture is called thermoelectric effect, also known as the seebeck effect. There are two kinds of closed loop of thermoelectric potential electric potential; Contact potential temperature and electric potential. Contact potential peer is refers to the two different conductor in contact; Electric potential and temperature difference is the same at both ends of the conductor potential occur with different temperature, different conductors with different electron density, electric potential so they happen nor, on the other hand, due to their different electron density of thus have certain electronic dispersion, when they reach a certain equilibrium of electric potential and contact potential depends on the size of the two different conductor material properties and their temperature contact point.
