Basic introduction of high temperature corundum protection tube 1600 degrees diameter 16mm 20mm

Thermocouple meters are commonly used in industrial production, of which * the key core parts are thermoelectric wire and insulation protective sleeve. Aluminum oxide ceramic insulation protection sleeve has good thermal conductivity and high temperature resistance, and it is widely used in the production of thermocouple. It plays a key role in protecting thermal conductivity wire and improving the service life of thermocouple. The corundum protective sleeve has a sealed round head shape at one end, and its tightness is good. It is generally used in conjunction with the insulation core to form an important temperature measurement element of the thermocouple protection tube.
