The laser sensors must be precisely aligned to ensure that the laser measuring system can measure precisely. To do this, the two laser sensors, which are located at the top and bottom of the C-frame, are aligned vertically and in the same position in relation to each other. The in-house pre-calibrated laser sensors are the basis for accurate thickness measurement.
During the laser-based measurement, the thickness of the strip is calculated from the results of the distance measurement of the two triangulation sensors arranged above and below the strip and the distance between the sensors. In addition to the measurement accuracy of the two sensors, the distance between the sensors is a crucial parameter for reliable thickness measurements.
