Basis weight measurement

The basis weight sensor is based on the attenuation of Beta radiation emitted by a nuclear source as it passed through a material. The basis weight is determined by sensor variation in the energy radiated by the source of known intensity.

  • Different types of sources available
  • Measurement range depending on source
  • Unprecedented accuracy
  • Default air gap: 12 mm (up to 20 mm)
  • Spot size: 12 mm
