X-Ray 2000: designed
for reliability
There is an increasing demand for measurement and control of insulation
wall thickness and eccentricity at insulating and jacketing lines to reduce
material over-consumption, start-up scrap and rejected cables due to
poor quality.
Sikora’s X-Ray 2000 offers continuous measurement, and provides full control
of process parameters when measuring eccentricity and wall thickness,
diameter and ovality. It is specifically designed for use on insulating and
jacketing lines.
Using X-ray technology the cable is transilluminated by X-rays. Measuring
values are continuously available, which allows a fast centring of the
crosshead and continuous control of the extrusion line in consideration of the
minimum values.
The measuring axes are arranged under 0, 90, 180 and 270°. The system is
applicable to round cables, but permits the measurement of eccentricity and
wall thickness of straight and pre-spiralled sector conductors.
Interesting possibilities for the
X-Ray 2000 can also be seen
in the measurement of foam
insulated high frequency cables
where, besides the measure-
ment of the eccentricity, the
degree of foaming and the radial
distribution of the foaming can
also be displayed.
For specific applications where
it is necessary to define the true
ovality of a product, Sikora
offers a triple-axis X-Ray 2000 T
system.
The additional third measuring
axis provides measurement in three planes at 6 points and thus precisely
calculates the ovality. For analysis of the X-Ray 2000 data and visualisation of
the measuring values, as well as automatic line control, the processor system
Ecocontrol 2000 is part of the system.
The Ecocontrol 2000 displays the measuring values, numerically and
graphically, on a high-contrast 15" TFT colour screen. The system is operated
intuitively via a touch screen. In the case of eccentricity, the wall thickness is
shown as an eccentric ring; the position of the thinnest insulation wall is
marked in colour.
As standard, the X-Ray 2000 has a statistical function for analysing the
measured results in a length or time-related trend diagram (with a zoom
function) combined with a chart showing the distribution of the single values
(statistical distribution curve).
In combination with the control module, Set Point 08, control of the wall
thickness or diameter is available. For highest product quality and precision,
and lowest possible compound consumption, Sikora offers the hot/cold
control module HC 2000, in combination with the X-Ray 2000 and a Sikora
Laser 2000 XY diameter gauge head.
With the hot/cold module HC 2000, the material shrinkage is continuously
calculated and taken into consideration by the control of the diameter/
wall thickness.
The factory-calibrated X-Ray 2000 device requires no further calibration.
