Rosemount™ X-well™ Technology with Rosemount 648 Temperature Transmsitter
Rosemount X-well Technology accurately measures internal process temperature without a thermowell or process penetration.
Safely record process temperature- no cutting pipes, calculating wake frequency or process shutdown.
  • Cut the cost of each temperature point by up to 29%
  • Save engineering & design time by up to 65%
  • Reduction in engineering design time by over 70%

Reduce Thermowell Design Time by More Than 90%
