Thermowell with Flange (Fabricated) - TW40-D, TW40-E

Brand: WIKA Instruments Ltd.
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
  • Good price/performance ratio
  • Wetted parts made of special material
  • Non-wetted parts (flange, connection components) made of stainless steel
  • Model TW40-D: Thermowell welded to one unit. Model TW40-E: Tantalum cover exchangeable
