Petrochemical thermocouple (resistance)

Petrochemical thermocouple (resistance), specially designed for petrochemical sector, can directly measure liquid, steam and gas medium and solid surface temperature in the range of -200℃-1600℃.

working principle:

  O The electrodes of a thermocouple consist of two different conductors. When there is a temperature difference between the measuring end and the parameter end, a thermoelectric potential will be generated, and the working instrument will display the temperature value corresponding to the thermoelectric potential.

  O thermal resistance is based on the principle of the relationship between resistance and temperature as a certain function. When there is a temperature difference in the measured medium, a thermal resistance will be generated, and the working instrument will display the temperature value corresponding to the resistance value.

Nominal pressure:

Generally, it refers to the static external pressure that the protection tube can withstand without breaking at normal temperature. The allowable working pressure is not only related to the material, diameter and wall thickness of the protection tube, but also to its structure, installation method, flow rate and type of the measured medium.
