Over 250 machines using virgin pulp to 100% recycled furnish committed to a single sensor for weight and moisture measurement and control, the need for nuclear safety training and licenses as well as the specialized service and safety requirements have been eliminated.


  • A single non-nuclear sensor for both weight and moisture
  • Ultra-fast infrared measurement measures fiber weight
  • No radiation safety licenses or procedures
  • Savings in fire protection procedures and training
  • OD measurement is available at 1 kHz speed and 5 mm spot size which no nuclear sensor can match
