The prescale multilayer films are available in nine variants to determine mechanical compressive loads from 0.05 Nmm-2 (Extreme Low) to 300 Nmm-2 (Super High). They are supplied on rolls of 3 to 10 m run length in widths of 270 mm or 320 mm. Sections for placement between contact points can be cut out with scissors. When pressure is applied, micro-color capsules inserted inside the film burst, so that load and pressure progression are displayed in color. Accuracies of ± 10 percent are possible.
For higher accuracies of up to ± 2.0 percent, a system consisting of a high-speed flatbed scanner, evaluation software and a calibration sheet is available. Cutouts and print progressions can be displayed on the screen as a 3D detail view. This allows reliable statements to be derived about the actual and target forces between components or at joints.
