The primary function is to provide electrical isolation between thermocouple wires while maintaining thermal stability, preventing signal interference and ensuring accurate temperature measurement across extreme temperature ranges.
Magnesium oxide offers excellent dielectric properties, high thermal stability up to 1200°C, good thermal conductivity for rapid response, and resistance to moisture absorption, making it ideal for precision temperature measurement applications.
Properly compacted mineral insulation provides optimal thermal conductivity that allows efficient heat transfer to the thermocouple junction while maintaining electrical isolation, resulting in faster response times compared to other insulation materials.
