The non-contact scanning of the web of material is carried out by detecting contrasts in light conditions.

• Resolution of up to 30,000 pixels by a microprocessor controlled CCD chip
  
  
• Adaptation of the viewing range to the specific application by selecting from a range of different lenses
  
  
• Adjustment of the camera parameters as a result of the change of material parameters with the machine running (no changeover time required)
  
  
• Quick set-up and camera alignment via an integrated graphic display
  
  
• Simple operation using standard integrated automatic functions (for example, the removal of interfering contrasts, compensation for contamination, white balance, and storage of the set-up values)
  
  
• The production and adjustment parameters can be transmitted more quickly and more securely by networking via the BST bus system

Because of its large scanning area the CCD camera is particularly suitable for:

• Digital scanning of web edges, printed edges or printed lines
  
  
• Web center-line guiding
  
  
• Web width measurement
  
  
• Control of tools or other machines (for example, tracing of cutting knives, etc.)
