In this QuellTech turnkey solution , the QuellTech Image Processing Software enables the individual definition of tolerance fields and the detection of long-term trends that can occur, for example, due to tool wear. At the same time, the software remains parameterizable for the user without further programming. The QuellTech thickness measurement consists of 2 or more laser line sensors, where 2 laser line sensors 180 Grand are facing each other and the material to be measured passes between them. This solution can be implemented with QuellTech Q4–Q5 or Q6 laser scanners. With this method of coating thickness measurement, many profiles are measured in the direction of movement of the medium and produce in the result a point cloud of the thickness or coating thickness, which can be detected immediately in the case of deviations from the tolerance, over the entire width of the material.
