GMS-B Measuring Cell for Bent Tubes

The measuring cell for bent tubes is a contact-free optical measuring system for measuring bent tube and wire parts. It takes only a few seconds to determine a digital image of the workpiece to be inspected by shadow projection, and to compare it to a stored model transmitted through the CAD interface to determine size accuracy.
