Ceramic protective tubes are widely used in situations where components such as heaters or thermocouples need to be isolated from high-temperature melt or corrosive gases or dust.

Alumina ceramic protection tube features:

High strength, corrosion resistance;
Good thermal conductivity;
In high temperature aluminum melt, it has a good non-sticking effect.
Long service life; The service life of pure silicon nitride material can be as long as several years;

Material: AL2O3
Temperature range: 0-1800℃
Application: vacuum furnace, industrial furnace, electromechanical equipment,electronic appliances, mechanical seals, insulation, etc

Why do thermocouples need ceramic tubes

Thermocouples are exposed to extremely harsh environments, sometimes to extremely hot fires, and sometimes to mechanical shock, moisture erosion, and other problems. In order to enhance the protection performance and prolong the service life of the thermocouple, ceramic tubes are usually used to protect the thermocouple.
Ceramic tube has high strength, high heat resistance, high corrosion resistance, high insulation and other outstanding properties, can protect the thermocouple from fire, mechanical impact, moisture and corrosion in harsh environments, reduce the failure rate of the thermocouple, so as to ensure the stability and accuracy of the measurement results.
In addition, the ceramic tube material itself has the characteristics of oxidation resistance, stability, high mechanical strength, can withstand high temperature, acid, humidity and other environments, maintain long-term stability, extend the service life of the thermocouple, and reduce maintenance costs.
