CENTERVIEW 8000

CENTERVIEW 8000

The most valuable system for cable production

8-point-eccentricity,
4-axis-diameter and
8-point ovality measurement

CENTERVIEW 8000 is a non-contact gauge head, specifically designed for production lines of all round, single conductor wires, and cables with single or multi-wire conductors and solid or foamed insulations. Typical applications are tele-phone wires and RF cables, LAN or coaxial cables.

The system measures online the eccentricity, wall thickness, diameter and the ovality of cables with high single value precision. The measuring values are taken from 4 axes (diameter) respectively at 8 points (eccentricity, ovality) and are visualized on the integrates display or at the processor systems ECOCONTROL 600, 1000, 2000 or 6000. The operator receives immediately clear information about eccentricity values that can be instantly used for control or centering of the cross head. This assures maximum material savings. The measuring system is suitable for product diameters from 0.25 to 25 mm.

CENTERVIEW 8000 automatically centers to the position of the conductor in the gauge head, without touching the object to be measured. As a result of the automatic gauge head positioning a complex, manual alignment of the device or a mechanic guiding of the cable before or after the CENTERVIEW 8000 is not necessary.

CENTERVIEW 8000 facilitates the work of the operator, convinces regarding freedom of maintenance, reliability and life-long precision. Start-up losses are minimized, cable quality permanently improved and simultaneously the productivity of the line increased.

Measurement of micro-coax-cables
For a number of applications such as mobile phones, LED displays or medical probes micro-sized wires are required. These cables have a conductor diameter of 25 micrometers with an insulation wall thickness of 80 micrometers. For these diameter ranges cable specifications have to be exactly realized in order to transfer high-frequent signals without loss.

A special edition of the CENTERVIEW 8010 is specifically suitable for the measurement of eccentricity, wall thickness, diameter and ovality of micro-coax cables with a product diameter from 0.05 to 10 mm.

Integrated monitor
Integrated in the CENTERVIEW 8000e (enhanced) is as an option a 7“ TFT-Monitor, which displays production data. The operation is easy and menu-driven via touch screen.

The scatter plot displays the distribution of short-term variations
The scatter plot is a visualization of the measuring values of the CENTERVIEW 8000 at the display and control system ECOCONTROL as well as at the monitor integrated in the gauge head. With the help of the scatter plot the distribution of short-term variations of the eccentricity is graphically displayed. Every single dot represents a single value of the eccentricity regarding value and direction. The distribution of the scatter plot highlights the standard deviation of the eccentricity.

A circular distribution of the single values of the eccentricity shows their range of variation. The representation helps to optimize the extrusion process with regard to a minimum standard deviation.

A ring type scatter plot indicates that there is a permanently rotating eccentricity value, which could be a result of a rotating (oscillating) conductor prior to the extruder crosshead.

An ellipse type distribution of the single dots can happen, if the conductor is oscillating or vibrating in one direction directly before entering the crosshead and which therefore causes eccentricity variations.

The standard way of representing eccentricity using a cross-section of the cable is very helpful for the operator when centering the crosshead. But only the display of single values in the form of a scatter plot gives the operator the necessary information to take suitable measures to minimize eccentricity.
