K type thermocouple every rise once, how much of a thermoelectric emfs can produce?

If you want to know how big k type thermocouple can produce thermoelectric emfs, must first understand the working principle of thermocouple.

the working principle of thermocouple: two different ingredients of conductor ( Called the thermocouple wire or hot electrode) Two ends synthesis loop, when the junction temperature is not at the same time, in the circuit will generate electromotive force, this kind of phenomenon called the thermoelectric effect, and the electromotive force called thermoelectric potential. Thermocouple is to use the principle of temperature measurement, which directly used for measuring the medium temperature is called at the end of the working side ( Also known as the measuring end) , on the other side called cold end ( Also known as compensation) ； The cold end connected to the display instrument or meter, display instrument will point out the thermocouple thermoelectric potential. Thermocouple is actually a kind of energy converter, it converts heat into electricity, using thermoelectric potential generated by the measuring temperature.

K type thermocouple is relatively commonly used thermocouple, and display instrument, usually record instrument and electronic regulator. K type thermocouple can be directly measured various production from 0 ℃ to 1300 ℃ in the range of liquid, steam and gas medium, as well as the surface temperature of the solid. K type thermocouple are typically installed by thermal components, fixtures and junction box and other major parts.

K type thermocouple temperature and thermoelectric potential relation is generally by K type thermocouple indexing table namely K type thermoelectric emfs CRT to, through the look-up table is: K type thermocouple every rise once, in different period of thermoelectric potential temperature changes is slightly different, generally in 0. 042, 0. About 041 mv.
