Extrusion International USA 4-2019

29 Extrusion International 4/2019 More than 8 years ago, iNOEX rec- ognized the advantages of this key technology Terahertz at a very early stage and developed it to the now trendsetting measuring tech- nique which is suitable for indus- trial surroundings. WARP portable is proven evidence of the compre- hensive know-how iNOEX pos- sesses in this field, the company is regarded as the inventor of mobile Terahertz. WARP portable, which has been developed on the basis of a so- phisticated chip-based radar technology is designed for the mobile and precise wall thickness measurement of extruded mono layer pipes, large-sized sockets and plastic sheets. Inline and of- fline random measurement checks can be carried out within seconds and very reliably with this mobile handheld system. „This innovation has found our ap- proval very quickly“, commended Depmer this device. „The battery- powered handheld system with a running time of approx. 8 hours meets exactly our needs in the pipe extrusion process. We are able to gain reliable measuring re- sults directly at the end of the vac- uum tank. This early measurement and thus the option to intervene at a very early stage have lead to enormous savings, up to approx. 40 m in the extrusion line, explains Stefan Depmer. Terahertz measurement is hardly dependent on temperatures, this makes extensive and repeated calibration processes unnecessary. Measuring is based on non-ioniz- ing electromagnetic radiation of very low power which is non-haz- ardous for humans. No coupling medium is required. WARP por- table offers non-destructive and contact-free measurement of wall thicknesses between 5 to 110 mm, with an accuracy of <50 µm. For Türkayan Güneyik, Operations Manager PE with WKT, the simple and uncomplicated handling are the key benefits. Two positioning aids for different pipe diameters which are included in the delivery make it very easy to position the device correctly on the measur- ing object. The measurement is triggered at the push of a button. Within seconds the wall thickness and timestamp are available on the display. An internal accelera- tion sensor provides additional information on the measuring angle of the device towards the pipe. Measuring data and mea- suring positions provide valuable information for the line operator. Based on this data he is able to carry out a fast manual centering of the extrusion die. The measuring data logger memo- rizes up to 100 measurements in- cluding timestamp and measuring positions around the pipe circum- ference. Data can be exported via USB stick or optionally download- ed by WIFI on a local computer. WKT uses this data for measuring data protocols in their data base. The simple and intuitive opera- tion is carried out via touch display made of smartphone glass. This robust scratch-proof and crack- resistant glass display plus the low weight, the very good light trans- mission and the sensitivity to touch offer the highest user comfort. The robust splash-proof design of the housing (IP54) offers good protection against water and dust in industrial surroundings. The Operation Manager of WKT also emphasizes the mobile us- ability, not only along the ongo- ing production process and for the different extrusion lines (PE, PVC), but also for final inspection tests or random checks of ready pipes in the warehouse. WARP portable is also used for monitoring suppliers. All common types of plastic such as PE, HDPE, PP, PA, PVC, are measurable. This innovative system for simple measurements within seconds has a globally proven track record of successful use with more than 100 systems sold to the market, West- fälische Kunststofftechnik is only one of the players among many satisfied customers. iNOEX GmbH Maschweg 70, 49324Melle, Germany www.inoex.de Westfälische Kunststofftechnik Sprockhövel, Germany https://wkt-online.de iNOEXWARPportable – Terahertz-based handheld systemfor high-precisionwall thicknessmeasurement
