Specification

The Proscan Magnum is a non-contact shape table for off-line measurement of flatness or shape of aluminium or steel strip. Stresses within the rolled strip mean a residual 'shape' remains within the material. This shape is evident when the strip is laid on a flat surface. The Proscan Magnum accurately measures and quantifies the latent shape in the sample and proving absolute values of wave heights, waves per meter and I units. Off line measurement is the most accurate method of measuring shape as there is no tension or stress in the material during the measuring process. This makes the Proscan Magnum particularly suited for measuring thin gauge material with very high flatness specification such as lithographic aluminium coil. The Proscan Magnum provides the user with full 2D & 3D mapping of the surface flatness

 

Measurement Technique

 

By means of a precision gantry system a laser measuring the sample height is scanned over the surface. For every X & Y co-ordinate position a height measurement (Z) is taken. The resultant X,Y,Z data file is used to calculate the surface shape. The shape is quantified by calculating the 'I' unit for each longitudinal scan.
