Extended Extended

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 a probe diameter of 6 mm, can be applied.

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

Features
  • 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 (cylindrical, spheric)
  • Sleeves for the compression fitting available in PTFE or SS 316
  • The 3.1.B material certificate (according to standard EN 10204) is selectable directly from the sale structure of the product
