SC Series Sheathed Thermocouples
Sheathed thermocouple is a temperature sensor that a thermocouple element is inserted into a metal protective tube (sheath) filled with inorganic insulating powders (highly pure magnesium oxide) and hermetically sealed. The sensor has excellent performance on insulation, air tightness and durability for long-term continuous use even at high temperature and under various adverse environments.
