2.2 Description
This thermocouple is used for temperature measurement in industrial applications. 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.
For the connection side, the thermometer is fitted with a case. The case design contains
the connection terminals.
This document describes standard versions of instruments. For applications in hazardous
areas special instrument designs are required.
For further information for operation in hazardous areas, see the additional information for the
corresponding ignition protection type (separate document).
