Function
Highly compact CCD cameras or wide band sensors contactlessly measure the material edges and supply one or more width values, depending on the requirements. These values can be displayed or also provided on an output for the purpose of quality control. Width monitoring is also possible with our systems.
Area of use
Web width measurement systems are used wherever the width of non-transparent webs must be monitored precisely and continuously.
Application
An interruption in the conveyor belt is necessary for width measurement systems. The web is measured using transmitted light and its height must not fluctuate at the measuring point.
