Protection Tube - TW70

Brand: WIKA Alexander Wiegand SE & Co. KG
Each protection tube or 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
  • Variable length and dimensions
  • Large variety of materials
  • Design TW70-K: Weld-in connection
  • Design TW70-L: Flange connection
  • Design TW70-M: Threaded connection
