Extrusion International 6-2018

31 Extrusion International 6/2018 20 years of experience in ultrasonics are one of iNOEX’s highlights and the brand name AUREX represents reli- able ultrasonic technology designed for the measurement of wall thick- nesses and diameters. AUREX MK 400 - a comprehensive solution AUREX MK 400 for pipe dimensions of 32 – 400 mm reduces the product weight per metre and thus the overall production costs significantly whilst narrow tolerances regarding the wall thickness, the diameter and the oval- ness are reliably adhered to. The large working range offers a high degree of flexibility and during changes from small to large pipe diameters, there is no need for sensor adaptation. The very narrow system is assembled in extrusion direction and directly on the vacuum tank. This makes a support- ing frame redundant in order to ac- count for the limited space available in an extrusion line. Quickly operational AUREX MK 400 is equipped with its own water collection tank including overflow device above the measuring chamber. It is ensured that the cham- ber is constantly and sufficiently filled with water. Thanks to the low water volume and the magnetic valve for fast and automated filling, the MK 400 becomes very quickly operational. Inside the system, air bubbles are able to rise to the top unhindered. The in- tegrated water filter prevents system pollution. Further, the system dispos- es of a water collection basin for drip- ping water. Perfect interplay of all components Double sealings on the inlet side sig- nificantly improve measuring results as any air bubbles are removed from the pipe surface. On the outlet side, MK 400 is equipped with only one sealing. The sealings on the vacuum tank and all sealing sets can be eas- ily and comfortably exchanged, quick fasteners on the inside and the out- side help to ensure this. As the pipe is frequently not centered when it leaves the vacuum tank, this applies in particular to pipes with a diameter of ≤ 160 mm, it is centered and optimally guided by an easily adaptable manu- al double-cone guiding device. This guide element can be easily folded away, no tools required. Precise measuring results Ultrasonic sensors which are continu- ously rinsed with water to prevent any air bubbles from disturbing the measurement, are precisely designed to generate, receive and process ul- trasonic echoes with the required ex- actness. Themeasuring electronics is a digital ultrasonic evaluation electron- ics with a highly precise performance and the proven AUREX software pro- vides a flexibility to solve any measur- ing task. This combination of a high- end electronics and an innovative measuring technology is able to eval- uate up to 7 product layers, starting at a wall thickness of 0,02 mm. The 21“ terminal based on a future-oriented and cross-platform solution permits the visualization as a website through easy integration via browser. Contin- ued access to the most important ap- plications is thus guaranteed. Comprehensive information Measuring data is logged, thus com- prehensive quality data can be pro- vided at any time. The same applies to detailed product information. Par- ticularly the adherence to very narrow tolerances of wall thickness, diameter and ovalness are of utmost impor- tance. Further, wall thickness sizes, thin points, weights per metre and mass throughputs can be controlled by an iNOEX gravimetric system. As such, the production process becomes reproducible and remains on a con- stant quality level. MK 400 carries out almost all measuring, control and doc- umentation tasks and can therefore be called a comprehensive solution for the automation of pipe extrusion lines. Durable and easy to maintain The robust product design makes it a very durable product. All cables and plugs are mounted outside the mea- suring chamber and inside the hous- ing. Therefore, they have no contact with water which makes MK 400 a low-maintenance system. Ultrasonic sensors may even be exchanged dur- ing the ongoing production process. Further, MK 400 can be easily folded away from the vacuum tank which provides easy access to the sealings of the tanks whenever they need to be exchanged.
