Sikora presents a 3-axis lump detector,
Lump 2000 T for fibre optic cables.
Sikora customers already benefit from
the measuring performance of the
2- and 3-axis lump detectors during cable
production. With the new special edition
of the Lump 2000 T Sikora offers an
additional future-oriented technology for
the detection of lumps and neckdowns in
transparent materials, in particular for the
production of fibre optic cables.
Gauge heads are available for product
diameters from 0.25mm to 10mm as
well as 0.5mm to 35mm. The heart of
the new lump and neckdown detector
is the technically advanced double
sensor technology. Using light sources
in combination with light sensors the
Lump 2000 T detects in three planes
the quantity, type, height and depth
as well as the length of the fault in the
transparent material.
Particularly useful is the success of
the lump detector for loose tubes.
These cable types consist of a hollow
transparent plastic tube that includes
a number of optical fibres. The cable
is filled with a water-blocking gel in
order to prevent the fibres from moving.
Conventional lump detecting methods
would have difficulties to achieve
accurate measuring results in these
conditions. The gel inside the tube
contains air bubbles, which function
like lenses at light incidence and
diffract the light.
Lump 2000 T technology ensures reliable
measuring results. The system defines
non-conformities in the product surface
– even at production line speeds of
up to 3,000m/min.
Even the smallest lumps and neckdowns
of 0.01mm are detected and analysed.
Under difficult conditions, such as
extreme vibration, the lump detector
ensures reliability readings at the fault
detection and as there are no moving
parts there is no need for calibration
or maintenance.
The Lump 2000 T offers diverse
interfaces such as RS485, RS232 for PC
diagnosis. Optionally, a Profibus-DP-,
EtherNet/IP- or DeviceNet-interface for
the direct connection to a PC or the
display and control devices respectively
Remote 2000 and Ecocontrol 600 are
available.
