Measurement systems for aluminium
LAP laser measurement systems operate on the principle of triangulation, light section or shading. These measurement methods detect distances or contours. In contrast to radiometric methods they are independent of the chemical or metallurgical composition of the material.
This means that all measurement methods of the steel industry are also applicable for non-ferrous metals.
Through mathematical and optical approximation methods, the measuring results are evaluated. Since the measurement is non-contact, hot materials can be directly measured after the continuous casting as well as cooled semi-finished and finished products.
Differences in the measurability only occur at the different surface properties of the material to be measured. Very highly reflective surfaces should be measured by other methods than laser triangulation, for instance. For strongly absorbing materials you may need to increase the laser power.
