44 Extrusion International 1/2020 MEASURING TECHNOLOGY Perfect Waves – New Inspection System excels as Quality Checker of Corrugated Tubing With the new inline gauge ProfilControl 7 S CorrugatedTube developed by PIXARGUS it is nowpossible to inspect the completewavy structure of corrugated tubing gaplessly. Newly developed algorithms enable, for the first time ever, the inspection of so far undetectable areas: not only the peaks and valleys, but also the transition areas in between. This inspection capability reduces out-of-spec production and will cut process costs At TUBE 2020, measuring specialist PIXARGUS is going to unveil its new system for the inspection of corrugated and spiral tubing. ProfilControl 7 S CorrugatedTube sets a new standard as it is the first ever inspection system capable of performing high-accuracy inline quality control of flexible tubing Even flaws too tiny for the human eye to discern are recognized by ProfilControl 7 S CorrugatedTube in a matter of seconds: holes, dents, blisters, nodes, scratches, fissures, for example, or poorly crimped joints are detected with 100 percent reliability Corrugated tubings have become a multi-talent in ma- chines, instruments and vehicles thanks to their extraor- dinary flexibility, which is rendered by their wavy struc- ture. The special structure that gives plastic tubing this unique flexibility used to be a very rough terrain for qual- ity inspection systems, because of the challenge of having to deal with a product surface that alternates between plane and curved structures. A reliable surface inspection system must be able to automatically differentiate be- tween the two and inspect them – continuously – accord- ing to different specific quality parameters. All this is now possible with the groundbreaking inspection system Pro- filControl 7 S CorrugatedTube (PC7 S CorrugatedTube) developed by PIXARGUS. An innovative sensor head and new algorithms assure total defect detection Using the successful technology of its proven PC7 S Tube inspection system, PIXARGUS has developed an entirely new sensor head for corrugated tubing. Eight high-per- formance cameras capture the surface structure of corru- gated tubing from different angles, inspecting not only the peaks and valleys, but also the transition areas. Entire- ly new algorithmic processes were developed to enhance the software which is now able to detect the change from plane to wavy and vice versa by masking out specific sur- face structures. This makes even extremely small flaws visible. Holes, dents, blisters, nodes, scratches, fissures or poorly crimped joints will be detected with 100 percent reliability. As a result, out-of-spec production of corru-
