Learn about the limitations of conventional thermowells and the benefits of the latest Rosemount™ thermowell design

This Technical Paper is loaded with information on the challenges you face with conventional thermowells. It provides a technical overview of why most thermowells fail and how to avoid it using Emerson's Rosemount™ Twisted Square™ Thermowell. You'll learn how to streamline calculations to save you money, engineering time and provide a safe solution for applications where you couldn't add a temperature measurement in the past or for process conditions that don’t pass ASME PTC 19.3 TW standards.

How will Twisted Square Thermowells help me improve reliability and reduce risk?

  • You’ll eliminate over 90% of dynamic stress, the primary source of thermowell fatigue failure
  • You’ll have longer-lasting sensors because of reduced thermowell vibration
  • You’ll have better thermowell sizing to get a more accurate temperature reading
  • You’re able to add temperature measurement in more places you need them

How will Twisted Square Thermowells save me engineering time and money?

  • Reduce engineering design time and simplify thermowell calculations
  • Have pain-free retrofits, avoiding complicated and expensive pipe modifications
  • Have safe operations when process conditions change (start-ups, shutdowns, events)
  • Have higher equipment availability due to less failures for more throughput

The Rosemount Twisted Square Thermowell has been third-party tested to ensure product quality and safety.
