Protection tube for temperature sensors ©Endress+Hauser

The protection tube with built-in compression fitting allows varying types of probes to be applied

This protection tube is well fitted with an integrated compression fitting, suitable for different industrial applications including even hygienic applications. By default, it is fitted onto pipes and vessels or tanks where attachment to the process can be threaded or welded. Due to its construction various types of temperature probes, such as compact thermometers as well as assemblies without a protection tube or cable probes, generally with an probe diameter of 6 mm, can be applied.

  • Benefits

    • The compression fitting allows for the replacement of the faulty probes without having to suspend the process underway

    • Different process connections can be selected as standard within the sales structure: Threaded (G ½", G ¼", NPT ½", ...); Weld-in (...

  • Field of application

    TW251 is a tube well fitted with an integrated compression fitting, suitable for different industrial applications including hygienic applications.
