Applications of High-Temperature 95% 99% 99.7% Alumina Ceramic Tube Structure Ceramic for Thermocouple Application

Alumina ceramic tubes are important for thermocouple protection. They are made mostly from aluminum oxide. Different purity levels exist: 95%, 99%, and 99.7%. Higher purity usually means better performance. These tubes handle very high temperatures well. This makes them good for thermocouples in hot places.

Thermocouples measure temperature. They need protection from harsh conditions. Alumina ceramic tubes shield the thermocouple wires. The high purity helps the tube resist heat. It stops the tube from breaking down quickly. A 99.7% tube generally lasts longer than a 95% tube under extreme heat.

These tubes are also strong electrical insulators. This is vital for accurate temperature readings. Good insulation prevents electrical signals from leaking. It keeps the thermocouple measurement reliable. The ceramic does not conduct electricity well.

The tube structure is hard and dense. It protects the thermocouple inside. The tube withstands physical bumps and scrapes. It also resists chemical attack from gases or liquids. This toughness helps the thermocouple survive tough industrial environments.

Factories use these alumina tubes in furnaces and kilns. They are common in metal processing and glass making. High temperature processes need dependable thermocouples. Alumina ceramic tubes provide the necessary protection. They help ensure the thermocouple works correctly over time. Choosing the right purity level depends on the specific temperature and conditions.

5 FAQs of High-Temperature 95% 99% 99.7% Alumina Ceramic Tube Structure Ceramic for Thermocouple Application

What are alumina ceramic tubes for thermocouples? They are protective sheaths. They shield thermocouples inside furnaces or hot areas. They are made from aluminum oxide. This material handles extreme heat well. It also resists chemical attacks.

Why use alumina ceramic for thermocouple protection? Alumina ceramic withstands very high temperatures. It keeps the thermocouple safe. It stops heat damage. It also prevents chemical corrosion. This means accurate temperature readings. The thermocouple lasts longer.

How hot can these tubes get? It depends on the alumina purity. Higher purity means better heat resistance. 95% alumina tubes work up to about 1600°C. 99% alumina tubes handle roughly 1700°C. 99.7% alumina tubes manage nearly 1800°C. Choose the purity based on your furnace temperature.

What is the difference between 95%, 99%, and 99.7% alumina? The main difference is purity. Higher purity means better performance. 99.7% alumina is the purest. It offers the best heat resistance. It has the highest strength. It resists corrosion best. But it costs more. 95% alumina is less pure. It costs less. It works for many applications. 99% alumina is a good middle option. It balances cost and performance.

How are these tubes installed? Installation is usually simple. You slide the thermocouple into the tube. Seal one end. Insert the assembly into the furnace. Ensure the tube fits your furnace port. Make sure it does not touch hot furnace walls directly. This avoids stress.
