Gap, spalt, valsgap, vals konvexitet
If two object edges are joined together, a gap always remains. If the gap has to satisfy technical or visual requirements, the course with respect to the size must be checked. If the gap should be measured completely, laser scanners in the scanCONTROL series are ideally suitable for this. Point laser sensors in the optoNCDT group are also used for precise gap measurement over a track.

DetaljerValsmellanrum
Vid valsning av metall, plast eller andra material är avståndet mellan de två valsarna eller mellan valsen och lagerytan avgörande. För känsliga processer som kräver hög noggrannhet är det viktigt att hela tiden kontrollera mellanrummet för att eventuellt materialslöseri ska kunna undvikas. För detta ändamål är induktiva eller beröringsfria metoder lämpliga.
