Annex A (informative) Remarks on the selection and operation of
protection tubes
This standard applies to straight thermocouples for the nominal pressure level PN 1, which are made of standardized components (connection head, protection tube and thermocouple(s)). Details regarding the operational areas of the thermocouples and the use of protection tubes are part of this standard. Connection heads as well as stop flanges and threaded bushings for the mounting of the thermocouples are also part of this standard. Special designs are to be agreed upon between manufacturer and user.
