Non-contact X-ray principle. Profiles are continuously scanned across the direction of production.

 As the material to be measured passes the gap between the X-ray source and detector, part of the radiation emitted is absorbed.

The weakened rate of radiation intensity is measured and indicates the weight per unit.

In cross-profile scanning, the profile is divided into sections, up to 128, and the measuring values are allocated to existing adjustable elements (e.g. an adjustable rake).

The data is then calculated based on average values.
