Extrusion International USA 6-2019

31 Extrusion International 6/2019 Radar technology is suitable for all common plastic ma- terials such as PE, L-/HDPE, PP, PA6/-12, PVC, PVDF, etc. without any limitations as to measuring accuracy. The transmission and receipt of radar waves does not re- quire any coupling medium which makes the applica- tion very robust, reliable and independent of produc- tion variability. WARP 100 is an inline pipe measuring system for wall thickness and diameter measurement on up to 38 points on 19 axes. More than 1500 measurements per second ensure that a gapless control is carried out on pipes that have to meet with particularly high-quality standards, e.g. pressure or gas pipes, at line speeds of up to 15 m/min. The WARP 100 in is available in three sizes and can be used to measure diameters from 90 to 630 mm. WARP uses static sensors which are aligned around the pipe. They measure the pipe continuously and in paral- lel. This is called a „real“ 100 % measurement as every spot of the pipe is included in the inspection process, independent of the pipe dimension or the line speed. The specially designed optical unit allows to focus the radar waves on the pipe centre. Sensors are aligned in a way to make measuring spots overlap so that a strict inspection is guaranteed in extrusion direction. Measured values such as wall thickness, diameter, oval- ity, eccentricity or process conditions (e.g. sagging) are recorded with high precision, then documented and used for automatic process control. The standardized process data interface OPC-UA offers further advan- tages for digitizing production. 191129_Extricom_Extrusion_Anzeige Extrusion International Magazine-Dez.indd 1 02.12.19 08:28 iNOEX GmbH Maschweg 70, 49324 Melle, Germany www.inoex.de WARP 100 – 100 % measuring spots overlap
