Precision measurement3
New laser devices will expand Sikora’s current range
of diameter gauges by three powerful models, said to
offer even higher precision and reliability, thus effectively
improving the efficiency of the production line.
The 2,500 measurements per second provide extremely
high single-value precision, ensure an optimum line control
and provide reliable statistical data. With the new measuring
devices the cable diameter is measured with an accuracy of
up to 0.2 micrometers.
Sikora engineers are said to have integrated a number
of practical improvements. The opening of the gauges is
twice as large as the measuring range, to ensure an easy
cable feed through. Directly integrated into the gauge
head is a new, pluggable universal interface module for all
connections. In this position it is protected against water,
dirt or mechanical influences during production.
A special feature, carried over from the larger Laser Series
2000 gauges, is the swivel gauge head design. It allows for
the gauge head to be easily moved up, out of the extrusion
line. The measuring axes are arranged in such a way that
the gauge is open at the bottom to prevent dirt and water
from falling into the measuring area.
Sikora offers the Laser 6020 XY for product diameters from
0.25mm to 20mm, Laser 6040 XY for a measuring range
from 0.5mm to 40mm and the Laser 6080 XY for products
from 1mm to 80mm.

FMS has expanded its product line of
wireless tension control solutions with
the new RTM X2 System, developed
to provide for the efficient and
accurate measurement, processing,
transmission, and evaluation of material
tension on rotating wire-processing
machinery. The expandable features of
the RTM X2 System make it suitable for
applications in bunchers and twisters.
Since the introduction of the original
PC-based RTM system years ago,
FMS has successfully provided many
wireless tension control solutions
for a wide range of wire and cable
applications, and continues as a
technology leader with the release of
the RTM X2 system.
The RTM X2 system can be utilised in
either a standalone configuration or
integrated with an existing PLC, and
thus is suitable for use by OEMs on
new machinery or by integrators and
end users when upgrading existing
machinery.
With the RMGZ series of force
measurement rollers and the 309 series
of digital electronics, FMS continues
the tradition of developing innovative
system solutions for tension monitoring
in rotating applications. When used
together the system provides improved
product quality, increased production
rates, increased operator convenience,
and allows for high data connectivity.
The RMGZ force sensors for wire
processing applications are available in
four configurations:
RMGZ100: To measure tension in
thin ropes, cables, wires, and fibres.
RMGZ100 is ideal where space is
limited, and is available in six nominal
force ratings ranging from 6N to 300N.
RMGZ300: This dedicated measuring
roller family was developed specifically
for use in higher RPM rotating
applications where the special design
effectively compensates for centrifugal
and Coriolis forces. It is available with
nominal force ratings of 50N to 1,000N.
RMGZ400 and RMGZ600: The
RMGZ400 and RMGZ600 series
sensors utilise an enhanced bending
beam principal. These products are
available with a nominal force rating
ranging from 60N to 4,000N for
medium tension requirements.
RMGZ800: This series of force
measurement rollers is used to
measure the tension in heavy ropes,
cables, and steel wires and is available
in eight nominal force ratings from
100N to 8,000N for higher tension
applications.
All variants of the RMGZ force
measuring rollers offer an overload
protection rating of ten times the
nominal force rating and a 20:1
force measuring range. The sensors
are constructed of stainless steel,
incorporate a full Wheatstone bridge
strain gauge, and include an aluminium
cover for corrosion resistance.
The 309 series of digital electronics
are an ideal complement to the full
FMS product line of force measuring
sensors. All units are available in wall,
DIN rail, and panel mount versions,
and include standard features such
as Ethernet interface, automatic
offset compensation and calibration,
and a fast 1ms cycle time. Products
include the EMGZ309 single channel
amplifier for total tension monitoring
and the CMGZ309 PID wire tension
controller.
These innovative FMS products are
competitively priced, and provide
the machine designer with the option
to access equipment from a central
location using modern Ethernet
connectivity.
