Threaded Thermowell or for Push-In/Weld-In, Fabricated - TW35

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
  • Version per DIN 43772. 
  • Model TW35-2: Form 2 (straight). Model TW35-3: Form 3 (tapered). Model TW35-4: Form 2G (straight). Model TW35-5: Form 3G (tapered). 
  • With integrated neck tube. 
  • Model TW35-3, TW35-5: fast-response design.
