Long products such as profiles, billets, etc., which are produced by rolling, drawing or forging, often have complex cross-sectional geometries. DimensionCONTROL measuring systems are used for geometrical inspection of long products. Depending on the application, these can be equipped with ThruBeam sensors, red and blue laser profile scanners to provide the optimal solution for the application. The systems operate with impressive precision even under the toughest hot rolling conditions. Integrated, fully automatic calibration compensates for the temperature-related, potential long-term drift of the mechanical structure.
