UltraScreen can monitor extrusion quality by measuring insulation layer thickness variation longitudinally, circumferentially, and through frequency analysis. It identifies two mechanisms causing oscillations in thickness around 15-20 seconds and 3 seconds periodically. This diagnostic information can help pinpoint unstable parts of the extruder head and improve extrusion mechanisms. UltraScreen is uniquely suited for this analysis through its rapid 16ms sampling of each of its 16 channels around the cable.
