A faulty temperature indicator led to non-uniform furnace temperatures

How SAM GUARD® Helped

  • SAM GUARD detected a problem with the temperature in a furnace, but no other abnormal findings related to the furnace
  • The plant team investigated and discovered that one of the temperature indicators was broken
  • They replaced the damaged indicator


  • Without an accurate temperature indicator, the bottom dryer temperature of the furnace rose dramatically
  • This led to non-uniform furnace temperatures, which in turn affected product quality
  • Replacing the temperature indicator helped maintain high product quality and prevent wasted batches
