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.
