High performance metal strip inspection

The completely updated inspection system for thickness and profile inspection of metal strip meets all the requirements of the sector. The system now provides a much larger measuring gap of 190mm, almost three times larger than its predecessor. Rather than using the previous point-type laser sensors, profile sensors are now used, which measure significantly better on corrugated strip materials and increase the monitoring range. The system enables thickness measurements down to 0.01mm accuracy and so is ideal for process stabilisation and quality assurance. Due to the use of a special high tech light barrier, edge detection of warped strips is possible, where individual strips can be documented over the complete process.

By replacing radiometric methods with optical measuring techniques, the system is wear-free and operates free of any emissions and works reliably with metal alloys. The measuring system for thickness and profile inspection is used for strips up to 4m wide and thicknesses of between 1mm and 12mm.
