With two inspection systems combined within one sensor unit, measuring specialist PIXARGUS has set a milestone in automated quality control of hoses, tubes and cables.

ProfilControl 7 DV Tube brings together surface inspection and diameter measurement within a compact design. Thanks to the multi-camera sensor system, it can perform various highly challenging measuring and inspection tasks at the same time. This is measuring performance at its best – combined with ultimate user friendliness.

Because all measured data are acquired by just one sensor unit,  the corresponding contour and surface information can be easily correlated. This takes data precision and defect analysis to the next level.

The inspection system not only provides measured data and evaluations in real time, but also processes quality-relevant data into a “defect map”. Intelligent Big Data analysis functions make the production chain of extrusion more transparent at critical stages. Repetitive defects are avoided. Production can be optimized in a pinpoint manner.

Highlights of ProfilControl 7 DualVision Tube

PIXARGUS Multi-Camera Sensor Technology

The PIXARGUS high-capacity multi-camera sensors guarantee 100-percent quality inspection of simple to highly complex products – everything from plain round products to multiple profile extrusion. Scalable system generation with modularly adjustable multi-zone scanning and PIXARGUS-developed lighting elements using LED and laser technology.


Intelligent operator guidance via a 21.5” multitouch screen and a clearly structured cockpit displaying all camera images and parameter settings make for easy and swift operation. Comfortable assistance systems, such as the automatic and simplified lighting control and focusing feature, reduce the set-up effort and eliminate operating errors.


“Big Data” becomes “Quality@ Industry 4.0”

ProfilControl 7 is Industry 4.0 ready, as it can be intelligently networked via LAN or other interfaces with additional sensors, measuring systems, PDA and ERP systems, and a PLC environment. It interlinks the quality data measured by the sensors and combines them into an integrated data map. Thus, the user can analyze the results within a coherent context and condense “big data” to what is really needed.


Maximum scalability and interaction within a network structure

ProfilControl 7 is a universal system supplied on a turnkey basis and designed to be switched between various lines as required. It can be scaled up to include additional networked components. This provides a maximum of flexibility and security of investment. Simply install the computer safely in the server room and place all the camera and sensor equipment in the line – scalability can be that easy!


Compact. Robust. Made in Germany.

The housing and wiring of the system have been designed specifically for service under most severe conditions. Thus they easily cope even with high mechanical stress. Tried and tested materials, ergonomic design and precision engineering guarantee longevity and provide security of investment.


Optional software modules for ProfilControl 7 DualVision Tube


DDM Module (DefectDensityManagement)

Checks the out-of-spec rate according to rules defined based on defect density and defect size.

Optical inline inspection systems have reached a high standard in detecting and classifying surface defects on profiles. However, the contextual evaluation of defects, which includes establishing logical relationships between defect criteria, has so far remained in the grey area.



In numerous specifications, especially those set up by automotive producers, the “ship or block” decision depends on OR-operations. A customer may reject a profile, for example, if over a specified length of the product there is one severe defect or one medium defect plus several small defects.

The Defect Density Management solution, however, weights every single surface defect and sums up the obtained values over a specified length of the product. The inspection system sends out a signal as soon as the value exceeds a defined threshold. The signal can be used to mark out-of-spec sections of profiles or control downstream cutting and sorting equipment.



Shiny Surface

Inspects high-gloss surfaces, as of chrome trims. Ideal also for curved surfaces.

What enhances the interior of vehicles or the appearance of stylish household appliances may become a real challenge in quality inspection. High-gloss chrome trims may give objects a dazzling appearance in the true sense of the word. The extremely intensive light reflection makes it very difficult to discern defects on the shiny surface.



To solve this problem, Pixargus’ Shiny Surface module casts structured light onto the high-gloss material surfaces. The pattern of light showing on the surface of the profile suppresses reflection while creating transitions of brightness that allow even extremely small scratches, bubbles or dents to be detected most reliably.

The system follows the exact contour of the product and inspects it over its entire width. The field of vision can be modulated so as to also enable the inspection of curved metal trims.



Multi Extrusion

Upgrade enabling simultaneous inspection of several extrusion strands.

Sealing profiles may also be produced by double-strand extrusion. In this case, the profiles are extruded symmetrically back to back.



To be able to measure the strands separately from each other, Pixargus has developed a special software module and added a dedicated frequency generator to its ProfilControl 7 system. The Multi Extrusion module inspects the geometry and surface of both extruded strands, while the frequency generator measures the speed and provides the optical sensors with data to adjust the image processing rate to the line speed.



Saw Control

Cuts your product to the correct length and cuts out defects with minimal waste.

With its Saw Control module, Pixargus makes cutting-to-length an integrated part of quality control in profile production.

The Saw Control software performs two basic functions. On the one hand, it sets the cutting intervals for the shear. If set at, let’s say, one meter, profiles graded as



defect-free by the quality control system will be continuously cut to this length and discharged from the conveyor belt as ready-to-pack products.

However, in the event that ProfilControl 7 has detected a flaw in the product, Saw Control instantly causes the shear to make an extra cut in real time to remove just the out-of-spec part from the profile.

This minimizes waste and saves time. Thanks to the Saw Control module, out-of spec portions of profiles can be sorted out much faster because the operators immediately recognize them as a short length comes along.
