Tension measurement
In the various processes of wire and cable manufacturing there are many
parameters that are measured and controlled. Of these, tension is among the
most important. The tension in wire or cable at the payoff and take-up points, as
well as during common operations such as drawing, stranding or extruding, plays
an influential role in process efficiency and product quality and performance.
A lack of tension measurement and control can lead to product defects,
substandard production levels and wasted money.
Tensometric’s new electronic tension meter,
Combi 490, offers precision across a wide
measuring range – up to 1,000 N. The unit
gives a digital display of measured values. It is
small (operation is one-handed) and is easily
threaded into the running material. Display
damping can be activated, to give a stable
and smooth display even during fluctuating
tensile forces. At the push of a button the last
indicated measured value is held.

Since 1983 Eldes has been producing
and installing real time control systems
for metal cold forming, both cold
headers and thread rolling machines.
The systems are based on the
measure of the force developed in
the production process, by means of
piezoelectric sensors applied to the
sensitive points of the structure. It is
thus possible to stop the machine if
anomalies arise.
Based on top-level technology and
experience, Eldes has developed a
new generation of process monitoring:
Helios 2K, supervises production in
metal cold forming plants using single
stroke multi-stations cold headers and
two blow cold headers. Titanus 2F is
the corresponding device for thread
rolling plants.
The instruments, with recently updated
software and keyboard, are designed
to be user-friendly and easy to use,
with refined features of signal analysis
and performances. They are available
in black and white and in colour.
Eldes’ project department is contin-
uously working on further development
of products and technology, on the
improvement of the user interface and of
measurement methods. Eldes can also
supply dedicated systems for customised
applications, in addition to the standard
instruments.
Dedicated technology for production
data collection (Prodat 2K) and
dimensional measures acquisition
systems (Themis) is also available.
