Thermowells serve two primary functions

  • Extend temperature instrument life by protecting sensing elements from harsh process conditions
  • Provide process isolation, enabling technicians to remove the temperature instrument for replacement or repair while the process system remains operational
  • SETEX thermowells are made from high-quality, thermally-conductive materials, providing long life and maximum temperature measurement accuracy.
