Sikora’s Centerview 8000 includes a non-contact gauge head to
provide continuous online measurements; 8-point eccentricity,
4-axis diameter and 8-point ovality measurements ensure the
highest accuracy. The system is suitable for the production of
coaxial, LAN, automotive and installation cables.
Sikora offers two Centerview 8000 versions, for product
diameters from 0.1mm to 10mm and 0.5mm to 25mm. The
Centerview 8000 combines an optical and inductive measuring
technique. With the inductive measuring circuit the position of
the conductor is recognised and the gauge head automatically
centred to the cable position. Guide rollers and manual
adjustment are unnecessary.
The optical part of the system is based on the principle of
diffraction analysis combined with pulse-driven laser diodes.
The laser diodes project a picture of the cable on the latest
available CCD-line technology in each measuring axis. Within
microseconds eccentricity, diameter and ovality are calculated
from the image of the product.
The cloud diagram is an additional visualisation of the
measurements being made on the processor system Ecocontrol.
With the help of the cloud diagram the distribution of short-term
eccentricity variations is shown. Each point represents an actual
single value of the eccentricity with regard to amount and
direction. The overall distribution of the cloud diagram easily
highlights the standard deviation of the eccentricity.
