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.
working principle
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.

Nominal pressure
Generally refers to the room temperature, the protection of the tube can withstand the static pressure without cracking. The working pressure is not only related to the material, diameter and wall thickness of the protective tube, but also with the structure, the installation method and the flow rate and the type of the measured medium.
