Thermocouple temperature sensor
- Product introduction：
- A thermocouple is a temperature sensing element and an instrument. It directly measures the temperature, and converts the temperature signal into a thermoelectromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument).

A thermocouple is a temperature sensing element and an instrument. It directly measures the temperature, and converts the temperature signal into a thermoelectromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument). The basic principle of thermocouple temperature measurement is that two different material conductors form a closed loop. When there is a temperature gradient at both ends, a current will flow through the loop. This is the so-called Seebeck effect. Homogeneous conductors with two different compositions are hot electrodes, the higher temperature end is the working end, the lower temperature end is the free end, and the free end is usually at a constant temperature. According to the functional relationship between thermoelectromotive force and temperature, a thermocouple graduation table is made; the graduation table is obtained under the condition that the temperature of the free end is at 0°C, and different thermocouples have different graduation tables.

Uses: used to measure various temperature objects, the measurement range is very large, far greater than that of alcohol and mercury thermometers. It is suitable for high temperature areas such as steelmaking furnaces and coke ovens, and can also measure low temperature objects such as liquid hydrogen and liquid nitrogen.
