Measuring the color of liquid paint is extremely complex. To date, paints have been typically applied on a test area first and then measured only after the drying process in order to achieve reliable measurement results. If the measurement results reveal that the paints are faulty, the paint containers must be mixed again or even disposed of which partly involves long waiting times until a new measurement process can be started. In order to accelerate this process, Micro-Epsilon has developed a system that enables the measurement of liquid paint during the production process.
This application therefore includes the colorCONTROL ACS7000 color spectrometer for color measurements and the optoNCDT 1420-50 laser triangulation sensor for distance measurements. The latter is ideally suited to this application due to its compact size and excellent performance. A linear unit offers automatic readjustments.
