Description

This high-temperature thermocouple with a gas-tight sapphire protection tube has been specifically developed for use in gas reactors. Through the monocrystalline structure, the sapphire protects the precious metal of the thermocouple from poisonous toxic media in the aggressive atmosphere of the gasification reactor.This patented solution has been used successfullyin different reactors worldwide since 1997 under the designation model T-FZV. Pressure-tight, hermetically sealed junctions between the sapphire and metal protection tube, and also a multifold sealing system in the connection case prevents toxic gases from being able to escape the reactor.The high temperatures and pressures in the gasification process place very high demands on protection tubes and thermocouples.These process conditions often lead to shut-downs and interruptions in operation. Utilizing the patented sapphire design can significantly improve life expectancy and reduce downtime. Applications Gasification reactors GtL reactors (Gas-to-Liquids) Sulphur recovery plants Special features 3 times longer service life in comparison to purely ceramic protection tubes due to the monocrystalline structure of the sapphire sensor High process safety with processes up to 1,700 °C (3,092 °F) and 65 bar (943 psi) Reduction of unplanned downtime Increased safety through double sealing system against escape of toxic media Cost savings through the elimination of a purge system and the repairability of the sensor
