Professional for the petroleum chemical industry design, direct measurement of 200million DEG C 1600 temperature range of liquid, steam and gas medium and solid surface temperature measurement.

The electrode of the thermocouple is composed of two different conductor materials. When there is temperature difference between the measuring end and the reference end, it will generate the heat potential, the working instrument will show the corresponding temperature value of the thermal electric potential.

Thermal resistance is the principle of the relationship between resistance and temperature. When the temperature changes in the measured medium, the resistance value also changes with the change, the working instrument will show the resistance value of the corresponding temperature value.
