Capacitance Measuring System

Sikora India offers an innovative Capacitance Measuring System, Capacitance 2000. This is a capacitance measuring device with 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). 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. Outstanding features: auto-adjusting stand-alone capacitance measuring system; unique Multi-Zone Electrode; reliable capacitance measurement and bare patch detection; and integrated FFT-analysis and SRL-prediction.
