Thermowell with Threaded Flange (Solid-Machined) - TW10-B, TW10-S

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
Each thermowell is an important component of any temperature measurement point.

It is used to separate the process from the surrounding area, thus protecting the environment and operating personnel and keeps aggressive media, high pressures and flow rates from the temperature sensor itself and thereby enables the thermometer to be exchanged during operation.
Features
  • Connection between flange and thermowell in threadwelded design
  • Model TW10-S: No directly wetted welded joints (standard). Model TW10-B: Additional weld seam on the process side (sealing joint)
  • Coating for corrosive or abrasive process loads
  • Possible thermowell forms:
    • tapered, straight or stepped
    • “Quill Tip” version (with open tip)
