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.
