RAYEX® - Overview


RAYEX® is a highly developed system based on x-ray tomography. During the extrusion process, RAYEX® measures the wall thickness, eccentricity, diameter, and ovality of multi-layer cables with XLPE and EPR insulation, multi-layer pipes with foam core, composite pipes, and multi-layer hose. RAYEX® systems have been in use for years on various production lines and processes with great success.

  • Steam - or steam/nitrogen lines
  • Catenary lines
  • Vertical lines

  • Horizontal MDCV lines ("long die")
  • In Silane, Sioplast/Monosil processes
  • In foam core pipe extrusion

Important Features:

  • Measures thin semi-conductor and insulation layers down to 0.3 mm (.012 in.)
  • Simultaneous and uninterrupted scanning in X and Y directions with highest precision
  • High scan rate and screen update (every 1...3 s)
  • Multi-colored, easy to understand display
  • Automatic control, thanks to short measuring intervals
  • High resolution and accuracy, thanks to "Micro Focus" beam and UMX x-ray source.

Your Advantages:

  • Shorter start-up times
  • Considerable material savings
  • Increased throughput
  • "Process transparency" at all times
  • Short payback
  • Seamless QC documentation

Typical Display Screens:

Cross-section of Multi-layer Cables, e.g.:

  • Medium Voltage
  • High Voltage
  • Specialty cables


The radiation intensity is far below all international limitation standards and, therefore, does not represent a safety problem.

Accuracy Check

Thanks to a special verification system, function and repeatability can be tested and proven any time.
