RAYEX® is a highly developed system
based on x-ray tomography. (Patents US 5 518 681, US 5 795 531,
and CH 685 336 A5). 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

|
Cross-section of Multi-layer Cables, e.g.:
- Medium Voltage
- High Voltage
- Specialty cables
|
Safety
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.
RAYEX® on CV Lines
 |
 |
Specific RAYEX® versions are available
for use on CCV and VCV lines operated with nitrogen
and/or steam. Conductor diameter and ovality can be
measured in addition by placing and ODAC® laser
measuring head in front of the extruder.
|
|
|
|
|
Depending on product and
quality strategy, and RAYEX® system can be
complemented with the following instruments to be installed
at the end of the line:
- Additional RAYEX® with "hot-cold" function
for automatic shrinkage compensation and monitoring of
the droop effect.
- Diameter measuring head ODAC®.
Special software allows automatic shrinkage compensation
and diameter control
- Surface inspection system SIMAC®

RAYEX® in
Silane Extrusion
Even medium voltage cable, single or
multi-layer, manufactured with Silane, Sioplast or similar
processes, can be measured directly at the extruder very
accurately. |
|
 |
| |
|
|
RAYEX® in
Pipe Extrusion
For foamed, multi-layer pipe and other
products, where conventional ultrasonic methods are not applicable.
In addition to wall thickness, diameter and ovality values,
the degree of blow is displayed continuously. |
