Rosemount™ Twisted Square™ Thermowell

Achieve accurate process temperature measurement and reduce the risk of thermowell failure in challenging environments with the Rosemount Twisted Square Thermowell. Its revolutionary design eliminates over 90% of dynamic stress, the primary source of thermowell fatigue failures, and provides a great solution for conventional thermowells that don't pass ASME PTC 19.3 TW evaluations.

Key Features

  • No Wake Frequency or Dynamic Stress Calculations
  • Eliminates over 90% of dynamic stresses
  • Improved reliability and reduce risk
  • Greatly reduces the risk of thermowell failures with changing process conditions (Start-up, Shut down, Events)
  • Easily expand to new applications
  • Ability to increase velocities for more through-put
  • Allows for longer insertion lengths for better temperature accuracy
  • Avoid complicated & expensive pipe modifications
  • Reduce Inventory (one thermowell fits all)
  • Use the same thermowell in different process conditions
