Long Lasting Stainless Steel Probe K Type Sensor High Temperature
Thermocouple
The basic principle of thermocouple temperature measurement is that
two conductors of different components form a closed loop. When
there is a temperature gradient at both ends, a current will flow
through the loop. At this time, there is an electromotive
force-thermoelectromotive force between the two ends. It is the
so-called Seebeck effect. Two homogeneous conductors with different
components are thermoelectrodes, the end with a higher temperature
is the working end, the end with a lower temperature is the free
end, and the free end is usually at a certain constant temperature.
According to the functional relationship between
thermoelectromotive force and temperature, a thermocouple indexing
table is made; the indexing table is obtained when the free end
temperature is 0℃, and different thermocouples have different
indexing tables.

Application
Thermocouples are widely used in science and industry; applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, and other industrial processes. Thermocouples are also used in homes, offices and businesses as the temperature sensors in thermostats, and also as flame sensors in safety devices for gas-powered major appliances.
