In-line measuring
CERSA-MCI has developed a common technology and software environment for a line of optronic measurement instruments for wires
and cables. Laser Sensor (LS) uses only static components, and has no moving parts. The range was originally designed for production
lines, as single units or in a network, and is widely used in laboratories.
The instruments provide realistic in-line measurements
and statistics without averaging. The standard refe-
rence wires come from different highly specialised
laboratories in different countries, to provide a
recognised international metrological reference.
Features of the range include:
Handling of diameters from 5µm to 2,000µm,
•
1 or 2 axes
Repeatability within 0.03% of the diameter limited •
to ±0.01µm
Temperature compensation from 10˚C to 40°C •
(50 to 104°F)
Capability to evaluate surface quality or roughness •
The following options are available:
Wire sample rotation (WSR) at constant tension •
Oscillating support (OS) for in-line ovality •
measurement
Battery power for portability •
Set of four reference wires for calibration and ISO •
certification: 30 to 2,000 microns ±0.1µm
The CERSA-MCI range is used in applications from metallic wires, fibres and filaments, to enamelled wires and drawing dies.

Creating the ‘Dogbone’ sample test piece used for tensile testing can be the point that
slows testing procedures and creates a backlog.
In the past, the common practice
has been to mill these samples. The
difficulty with milling is that it is
a slow process and can become a
bottleneck in the testing process.
A lapse of days between material
production and testing can result in
material being shipped before the
testing is completed.
With the Vale sample press a sample
can be quickly, easily, and accurately
created for testing so that tensile and
elongation tests can be completed
in good time by the metallurgical
laboratory.
Tensile test sample (dogbone)
presses can be used to quickly stamp
accurate samples, from the thinnest
material up to 12.5mm thick, and the
presses can be designed to punch
either the small 10" samples or the
larger 20" samples.
