Extrusion International 6-2019

26 Extrusion International 6/2019 MEASURING TECHNOLOGY Particularly in large-diameter pipe production, significant technical challenges have to be mastered in order to produce large-diameter pipes with uniformly thick walls and smooth surfaces. The iNOEX radar measurement technology is a key technology for measurement and quality assurance Advancement WARP XXL The system for large pipes up to 3500 mm WARP XXL is a highly precise pipe measuring system for wall thickness and diameter measurement of 8 to 32 measuring spots on 4 to 16 axes. The system is based on the latest iNOEX radar sensor technology. The innovative radar chip, the specifically designed lens geometry and the high-power electronics are the core parts of this future-oriented technology. The sys- tem supplies exact measuring data and offers a very simple operation. Due to the particularly flexible and modular sensor technology, 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 occur- rence of sagging. Sensors and their measuring spot on the pipe are automatically realigned so that even the smallest variations 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 WARP XXL – High-precision wall thickness and diameter measurement for large pipes up to 3500 mm 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 3500 mm. It measures (depending on the material) wall thickness sizes between 5 to 250 mm. All iNOEX WARP systems offer further advantages such as an ex- tremely minimized space requirement in extrusion di- rection, a user-friendliness and the smart maintenance concepts which can be carried out during the ongoing production process. A complete documentation of the production process in a data bank and the standard- ized process data interface (OPC-UA) conform to the current state-of-the art industrial standard. WARP Radar technology – Plastics measurement of the future Many have heard of the term radar technology in con- nection with distance measurement in the automo- tive or aviation sector. However, the measurement of thin-walled plastic pipes places higher demands on the electronics because a high-resolution capacity is a must when thin layers are measured. Due to the absence of a suitable product in the market, iNOEX decided to re-invent the core part of radar, the radar technology itself, including the appropriate pre- cision technology and optics, and to adapt the pack- age to the needs of the plastics market. Together with the best experts of the industry, a sensor technology was created that has the right solution for every re- quirement related to the measurement of pipes.
