The EF series is a non-contact eccentricity measuring device, specifically designed for themeasurements of eccentricity ,wall thickness, diameter, ovality, surface lumps and necks ofwires and cables. The operator receives immediately clear information about eccentricityvalues that can be instantly used for control or adiusting the extruder head.so as to makesure the wall thickness and diameter of the cable are kept at the optimal size.This assuresmaximum material savings.
Appolication
The EF series is suitable for all round single core or twisted conductor cables as well as multi-conductor cables, especially for coaxial cables, LAN cables, automotive electronic wires,
etc.
Measurement principle
The EF series eccentricity measuring device combines electromagnetic measurement technology and optical measurement technology. Multi-axis optical measurement system responsible for measuring the outer diameter, ovality and position of the cable insulation
layer, while the multi -axis electromagnetic measurement system is used to determine the position of the conductor core.
Optical and magnetic measurements are synchronously conducting measurement at a veryhigh rate, minimizing errors caused by wire vibration to the greatest extentpossible.Besides,the two measurement control is on the same plane, eliminating measurement errors caused by twisted wires and cables.
