Product Description

High Alumina Ceramic Chamber Domes are used when conditions exclude the use of metal, either for chemical reasons or because of excessive temperatures.Their main applications are between 1000 and 1800°C. They may be in directly contact with the medium or may be used as a gas-tight inner sheath to separate the thermocouple from the actual metal protection tube.

Ceramic Liners should be mounted in a hanging position above 1200°C to prevent distortion or fracture due to bending stresses.
Evenhair-line cracks can lead to contamination of the thermocouple resulting in drift or failure.

Techanical Ceramic provide a broad range of engineering properties:

High Temperature-Superior Strength-Corrosion
Resistance-Thermal & Electrical Insulation along with other specialized characteristics.
