Description
This high-temperature thermocouple with a gas-tight sapphire protection tube has been specifically developed for use in hydrogenous atmosphere.
Through the monocrystalline structure, the sapphire protects the noble metal of the thermocouple from poisonous toxic media in the aggressive process atmosphere.
Hermetically sealed junctions prevent toxic gases from being able to escape the reactor.
The high temperatures in the process place very high demands on protection tubes and thermocouples.
These process conditions often lead to shutdowns and interruptions in operation.
For further approvals, see page 8
Special features
- Cost saving by non-purge system
- Reduction of unplanned downtimes
- Increased safety against escape of toxic media through double sealing system
- High variance of thermowell / protection tube materials
- High process safety with processes up to 1,700 °C [3,092 °F]
