3-axis surface fault detection

For continuous quality control, lump and neckdown detectors are as important as diameter gauges and spark testers. Zumbach’s new line of KW 13TRIO detectors capture with high accuracy, reliability and velocity even the smallest lumps and neckdowns in wires, conductors, optical fibres, cables, tubes and hoses. With its compact design the KW 13TRIO can easily be integrated in any extrusion line or rewinding process. The measuring field is dimensioned in such a way that during start-up even extremely large lumps pass smoothly through, and its open design enables quick and easy threading of the product without stopping production. A powerful microprocessor and full digital signal processing make this lump and neckdown detector an essential tool for faultless quality control. The detector is, in addition to other versions, also available as a stand-alone device. Thanks to a local operating and display unit, the KW 13TRIO can
