Capacitance 2000 assures loss-free data transmission

For all LAN, coaxial, telephone or RF cables the loss-free transmission high frequency, analogue or digital signals is a major quality feature.

In this context, the measurement of the capacitance 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 measuring device which is installed in the cooling trough and measures the capacitance of the wire insulation precisely. At the same time, the system determines capacitance changes, provides an extremely fast measuring value update and detects bare wires. This technology is realised by the combination of one short and two long measuring electrodes, which are integrated in a measuring tube. The short measuring electrode of 10mm length identifies periodical capacitance variations with high spatial resolution by means of Fast Fourier Transformation (FFT).
