In rolling mills for heavy plate, the remarkable ratio between measuring range and precision comes into effect, which is achieved by using discrete laser line technology and by embedding a best-fit line into the point cloud of the sensors, which increases the resolution significantly. High linearity is achieved due to efficient signal processing.
Geometrical measurements based on radioactive radiation
Iterative calibration compensation for thermal effects
Large measuring range with high precision
Mechanism protects lenses from dirt
Comprehensive analysis software with numerous graphs for cross-sections, longitudinal profiles, SPC analysis and false-colour representation
The MTS 8202.LLT is equipped with laser triangulation scanners which means measurements are independent of the surface properties of the target material. Scaling or mirror effects of the metal surface are therefore absorbed. Furthermore, compared to point sensors, the system offers higher accuracy and a larger mouth width. Automatic inline calibration ensures that measurements are unaffected by temperature changes. The measurement line is arranged vertically to the material flow, enabling the system to cope with lateral strip tilting.
