25 Extrusion International 1/2017 MEASUREMENT Zumbach RAYEX ® S – X-Ray Measuring and Control Technology for Single and Multilayer Products In order for a manufacturer to select the measurement and control solution with the best price-performance ratio, the suitable technology must be chosen. After many years of experience in using eccentricity gauges with X-rays and ultrasonic, laser diameter and inductive measurement devices for different products and material, ZUMBACH expand the X-RAY family for dedicated tube and hose applications. ZUMBACH’s static X-ray system RAYEX ® S has especially been developed for any kind of foamed pipe, vulcanized products, hydraulic hoses, etc. RAYEX ® S measures and controls diameter, ovality, wall thickness and eccentricity of single and multilayer products with up to four layers. It provides precise measuring values and highest reliabil- ity for pipe and hoses with an outside diameter of up to 80mm. The system features the latest X-ray technology and software solutions. In combination with the data aquisition and processor system, an automatic control of the line is possible. By controlling line speed or extruder speed the parameters are controlled to the nominal value. The display shows all measurement values numerically and graphically as well as trends and statistical data. A line presentation with pictograms of the connected devices provides a clear overview to the operator. At thhe same time, the system reduces the wall thickness to a minimum value. Quality assurance and the reduction of material lead to a signifi- cant increase of productivity. Key Features and Advantages • High stability and accuracy - Repeatability typically with in ± 0.02 mm • Measuring frequency up to 10 Hz (in standard mode) • Simple concept and easy to use - 4 wall thickness points, 2 diameters, ovality - 2 X-ray sources positioned at a 90° angle - No recalibration is necessary but can be done if required - Integrated exhaust device for keeping measuring win- dows always clean • High safety level of the X-ray sources - Unique screening concept - Minimal scatter, no lead inside the equipment - Outside radiation level meets national and international standards • X-ray sources - Extremely robust and stable - Easy to exchange, no realignment - No water cooling required www.zumbach.com Measuring unit RAYEX® S
