Technical Overview
Thermocouple feedthroughs carry temperature measurement across the vacuum boundary with minimal error, sealing Type C or Type K couples in a ceramic insulator. They are rated for bakeout and high-temperature processes up to 2320 °C.
Typical Applications
- Furnace and thermal-processing vacuum systems
- CVD/PVD substrate temperature monitoring
- Cryogenic and bakeout temperature control
- Scientific vacuum experiments
