8-point eccentricity measurement

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.
