THERMOCOUPLE FORMED WITH THE POROUS INORGANIC MATERIAL OUTSIDE LAYER FOR THE HIGH TEMPERATURE CONDITION

摘要

PURPOSE: A thermocouple for measuring high temperature with a porous inorganic layer in the outside is provided to effectively prevent the disconnection of a thermocouple wire by effectively protecting the thermocouple exposed to high temperatures for a long time, thereby extending a lifespan. CONSTITUTION: A thermocouple(20) for measuring high temperature with a porous inorganic layer(40) comprises an outer housing unit(30) and a perforated support section(35). The outer housing surrounds the exterior of the thermocouple. The porous inorganic layer is charged inside the outer housing unit. The porous inorganic layer is a perlite layer.
