Extrusion International 6-2019

36 Extrusion International 6/2019 MEASURING TECHNOLOGY FOR ROUND PRODUCT contours of tubing, tubes and cables gaplessly, continuously and around the complete circumference of the products – with one single sensor head. A real novelty! An additional advantage of the new two-in-one gauge is its extremely compact de- sign, which makes it very easy for op- erators to integrate the system into their production lines. “Reduced to AllRounDia DualVision (DV) com- bines PIXARGUS’ vast know-how and expertise in an ideal way: the hardware and software of PIXAR- GUS’ highly successful ProfilControl 7 technology have been optimized and adapted to the measurement of product of simple, round contours. The result is a small-budget system that measures both the surfaces and the max”: this is how the PIXARGUS experts call this design approach. They are convinced that the new sys- tem will make a lasting contribution to the quality of round products. Measurement of dimensions: All-round instead of nodes measurement AllRounDia DV is the first gauge to deliver gapless 360° measurement of round and oval contours. PIXARGUS achieves this by employing a camera- based, laser-triangulation method. While conventional axis-based mea- surements using the shadowing method (see illustration) cover only six single points, the optical sensors of AllRounDia DV capture 8 million pixels. PIXARGUS Managing Direc- tor, Jürgen Philipps, knows: “Each in- dividual point can be decisive for the quality of the product.” Although the single-point method measures each single point very accurately, it does not capture the area between the points and detects only defects of relatively large topographic ex- tension (nodes). ”This can be illus- Themarket launch of AllRounDia DualVision is PIXARGUS’ answer to themarket’s demand for cost- efficient 360° inspection of round product. This two- in-one systemof extremely compact designmeasures and inspects tubing, tubes or cables with a 100%defect detection rate. Also regarding the price, this smart defect detector can score points First Single-Unit System Performing Complete Contour Measurement and Surface Inspection at the Same Time AllRounDia DualVision – the first single systemperforming complete 360° contour measurement and surface inspection of round product at the same time In contrast to conventional (6-point) axis-basedmeasurements, the optical sensors in an AllRounDia DualVision gauge capture 4 million pixels, guaranteeing gapless inspection around the complete circumference without any dead zone effects
