The right scanning system for each type of material.
The current position of the web is the basis. It is captured by one or more sensors as actual position.
Ultrasonic Sensors (US) :The scanning of the web edge is realized contact-lessly by ultrasound.
Optical Sensors (IR) :Non-contact scanning of the web edge is carried out by light.
Contrast Sensors (CLS Pro / CCD Pro) :The non-contact scanning of the web material is carried out by detecting optical contrasts.
|Insensitive to dirt and changes in the transparency of the material|
|No changes to the measured values through flutter of the web in the sensor scanning area|
|Compensation for any interference which may be caused by external sound sources or other environmental influences|
|Visible light (insensitive to external light sources by an internal compensation of the ambient light)|
|No influence on the measurements by flutter of the web within the light path|
|Optional connection for air jet protects the lens against contamination from paper, dust or other contaminants|
|Large proportional scanning band permits web center-line guiding even for relatively large web width variations|
|Precise scanning of lines, print edges or web edges using a color sensor|
|Optimum lighting thanks to automatically controlled LEDs|
|Outstanding dependability even at the highest web speeds|
|Clear color display|
|Minimal set-up time realized by intuitive user guidance and convenient operation|
|Laser guided positioning|
|Realistic picture of printed line, print edge or web edge shown in a color display|
|Removable control unit allows comfortable handling, even when it is installed in places, which are hard to get to|
|Remote control of basic controller functions|
|Resolution of up to 30,000 pixels by a microprocessor controlled CCD chip|
|Adaption of the viewing range to the specific application by selecting from a range of different lenses|
|Camera parameters adjustable for change of material while machine is running (no change-over time required)|
|Quick set-up and camera alignment via an integrated graphic display|
|Simple operation using various 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 eltromat bus system|
