Silicon Nitride Thermocouple Protection Tube
Manufacture Process
Moulding：Cold Isostatic Pressing(CIP)
Sintering:Gas Pressure Sintering(GPSN)
Feature：
High strength & good compactness.
Low thermal expansion coefficient
Excellent thermal shock resistance
No wetting by molten aluminum and other non-ferrous molten metal
Good corrosion resistance
Application:
Used to protect the temperature-measure components, make the components isolate from the outside substance, reduce and prevent the corrosion, oxidation and mechanical damage to the components during measuring.
Thermocouple is a widely used temperature probe, its long-time stability and service life will be up to outside protection tube. Thermocouple with silicon nitride thermocouple sheath will quickly react to the temperature due to the good thermal conductivity and thinner wall thickness of silicon nitride tube. Silicon nitride thermocouple protection are for continuous temperature measurement and protect thermocouple without erosion.
