CAPACITANCE 2000
Innovative capacitance measuring
Capacitance measuring devices with single and multi-zone electrode with ultra high frequency and length resolution as well as bare patch detection
For all LAN, coaxial, telephone or RF cables the transmission of high frequency, analog or digital signals at minimum loss for the signal amplitude is an essential quality feature. In this context, the measurement of the capacitance already at the cable production plays an important role. The capacitance influences the impedance of the cable for the specified frequency range and thus the quality of the cable significantly.
CAPACITANCE 2000 is a capacitance measuring device, which is installed in the cooling trough. It measures online precisely the capacitance of the wire insulation and reliably detects bare patches. At the same time, the system recognizes periodical capacitance changes and determines the Structural Return Loss (SRL).
Multi-Zone Electrode
Unique is the combination of one short and one long measuring electrode (multi zone technology), which are integrated in a measuring tube. The short measuring electrode of 10 mm length identifies periodical capacitance variations with high spatial resolution by means of Fast Fourier Transformation (FFT). From the FFT data, the SRL is determined and gives information about the expected attenuation of the RF signal during data transmission. The long measuring zone measures with high precision the average value of the capacitance.
CD-Control (Capacitance/Diameter-Control)
Precise measuring values for the capacitance and the diameter, as they are provided by the mentioned capacitance and diameter measuring devices of the LASER Series 2000/6000 respectively CENTERVIEW 8000, are the basis for a perfect CD-Control.
The CD-Control assures that the capacitance and the diameter comply with the requirements. This is achieved by an automatic adjustment of the cooling trough and with the control of the line speed. Both influence quantities are controlled by the ECOCONTROL 2000 or 6000.
FFT-Analysis and SRL-Prediction
The detection of periodical capacitance variations and the prediction of the Structural Return Loss (FFT and SRL) are available as special features directly at the measuring tube via a diagnosis interface. For displaying the FFT/SRL relevant measuring values the processor systems ECOCONTROL 2000 and 6000 are available.
