One of the most advanced inline colour measurement systems in the world – the colorCONTROL ACS7000 has been expanded with a new ACS2 circular sensor model. As well as the standard measurement spot sizes of 5mm and 9mm, a sensor is now available with a measurement spot size of 3x2mm. The small, oval measuring spot offers advantages primarily on curved surfaces. The curvature radius should be at least 20mm (previous models were at least 50mm). The new sensor head can also be used for inline quality control of structured surfaces that would otherwise be difficult to detect, e.g. wooden veneers, floor coverings and textiles. The inline colorCONTROL ACS colour measurement system with its six sensor head options offers application flexibility and has been successfully installed on in-process colour control systems for the automotive industry, as well as in medical engineering, plastics and textile production.
