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
be fully operated and configured
at the device. A unique measuring
principle and complex optics solution
ensure immunity to stray and intense
light whilst providing high detection
accuracy and identification of lumps
and neckdowns in the micrometre
range.
The minimum detectable fault height is
0.01mm (0.0004"), and the minimum fault
length is 0.2-0.3mm (0.008"-0.011").
