High Temperature Thermocouple for Blast Furnace and Airheater

Product Description

Operation theory :

Thermocouple electrodes are made of two different materials temperature diffference between measuring end and reference end results in pyroelectric potential ,then display meter indicates the corresponding temperature to the pyroelectric potential .

It is based on that temperature change of meterial results in change of its resistance.when resistance value changes,the working instrument will display relevant temperature value.
