Extrusion International 5-2019

48 Extrusion International 5/2019 MEASURING TECHNOLOGY iXRAY systems can be complemented by iXACT diam- eter measuring systems which are able to carry out up to 16.000 measurements per second per axis. They are fre- quently used for pipe or tube diameter measurement at the end of the extrusion line and they are implemented in the loop control for shrinkage calibration. iXACT – Impressive optical diameter measurement These systems based on semiconductor sensor technol- ogy and high-power LED are able to measure strongly vibrating tubes thanks to their high measuring sequence frequency. The high-power LED make measurement of most transparent materials very simple. The Plug & Play solution which does not need any calibra- tion also offers a difference function which registers any sudden variations. As such, it is possible to detect irregu- larities (e.g. knots, necking) on the measured extruded surface. An additional camera helps to compensate measuring er- rors due to inclination. This in turn increases the accuracy of the diameter measurement. The 2 or 3 axes measurement that operates at high speed and with a high precision is available in 3 different ver- sions: for products with a small diameter, for diameters up to 30 mm and for diameters up to 120 mm. The robust design of the system ensures that knocks or temperature changes do not have any effect on measuring results. In addition to the highlight of the new x-ray technology, iNOEX presents their advancements in radar sensor tech- nology for the plastics materials industry which is very likely to secure the decisive competitive advantages. iXACT – Impressive 16.000measurements per second WARPXXL –High-precisionwall thickness anddiametermeasurement for largepipes up to3500mm WARP XXL – The system for large pipes – nowup to 3500mm WARP XXL is a highly precise pipe measuring system for wall thickness and diameter measurement of 8 to 32 mea- suring spots on 4 to 16 axes. The system is based on the latest iNOEX radar sensor technology. The innovative ra- dar chip, the specifically designed lens geometry and the high-power electronics are the core parts of this future- oriented technology. The system supplies exact measur- ing data and offers a very simple operation. Due to the particularly flexible and modular sensor tech- nology, even pipes that show a strong eccentricity can be measured for the first time. As such, it becomes possible to exactly identify and quantify the occurrence of sag- ging. Sensors and their measuring spot on the pipe are automatically realigned so that even the smallest varia- tions from set standards become evident. This sagging alarm function implemented early on in the extrusion process offers an enormous cost savings potential. Further, the number of sensors is flexible which means that the concentration of sensors can be increased in the trouble spots of the process – for example in lower angle positions. Thus, optimum conditions are created to centre large pipes early on in the process in order to save materials and costs. WARP XXL is available for diameter ranges from 630 to 3500mm. Itmeasures (dependingon thematerial)wall thick- ness sizes between 5 to 250 mm. All iNOEX WARP systems offer further advantages such as an extremely minimized space requirement in extrusion direction, a user-friendliness and the smart maintenance concepts which can be carried
