28 Extrusion International 4/2019 MEASURING TECHNOLOGY – CASE STUDY Mobile and high-precision wall thickness measurement Stefan Depmer, Head of Technologies and Operations with the company WKT still remembers former days when reliable and efficient wall thickness measurement was carried out by ultrasonic devices but only at the end of the pipe production process due to different temperature gradients in the pipe wall. A check at such a late stage and the late intervention into the process resulted into a high scrap rate. WARP portable – the iNOEX handheld system based on Terahertz technology offers high-precisionwall thickness measurement – the perfect solution for WKT WARP portable used by Westf ¦ lische Kunststofftechnik (WKT) WARPportable infieldusewithWKT.
