High Temperature Alumina Ceramic Sheathed Thermocouple
This is a high-temperature thermocouple with an alumina (corundum) ceramic sheath, designed for extreme temperature measurement in harsh industrial environments. The high-purity ceramic protection tube provides excellent resistance to high temperatures, oxidation, and chemical corrosion, making it ideal for measuring temperatures up to 1600℃. The assembly includes a flameproof terminal head and optional flanged connection for secure installation in furnaces, kilns, and high-temperature process equipment.
