Laser sensors for a wide
range of applications
Cersa-MCI, France, specialises in the
design and development of optical
metrology such as laser diffraction
sensor (LDS series) for fine wire diameter
measurement, laser projection sensor
(LPS series) mainly for the cable industry,
as well as laser interferometric sensors (LIS
series) suitable for the fibre optic industry.
In order to meet increasing demand for in-
line defect detection of wires, optical fibres
and cables, the company has developed
SQM – Surface Quality Measurement
– using the latest optic and electronic
technologies. The company claims that
SQM pays for itself quickly, by improving
production efficiency and restoring quality
reputations for producers.
Two different principles are used
according to the applications: SQM
Fine (from 0.05mm to 2mm) checks 64
dots minimum per circumference with
330,000 circumferences per second, and
is aimed at application on fast lines such
as optical fibre, fine wires, and micro
tube. SQM Large includes three models
covering 0.5mm to 80mm diameters, and
offering 3,000 dots at 20kHz per range
circumference for extrusion applications.
Features of the instrument line include
adjustable defect detection thresholds
for shape, surface and frequency;
temperature compensation; serial link RS
232C/RS485; network connections; wire
length pulse count and speed computing;
statistical functions for defect size,
frequency and density; and static relay
outputs for alarm.
The company’s solutions for wire and
cable diameter measurement include
measurement by Laser Diffraction Sensor
New (LDSN) from 5 to 2000µm (0.2 to 80
mils), featuring stability and repeatability
within 0.03% of the diameter. Options
include wire rotation, label printer,
standard wires, portable units, and
oscillating support.
Cersa also offers a portfolio of high-
performance laser interferometric
measuring instruments that ensure full
fibre qualification and certification on
the draw towers. These instruments are
suitable for use with telecommunication
fibres, special fibres, GGP, and single
coating layer.

Evolution from Reelex
Reelex Packaging Solutions – formerly
known as Windings Inc – is busy with
more than just a new name.
The Reelex® package, an industry
standard in the communications
cable market, is evolving to address
the needs and requirements of a
broad spectrum of products that
are traditionally packaged on reels.
The size of the products packaged in
Reelex coils now includes products
with diameters as small as 0.025" or as
large as 0.625" outside diameter. The
resulting coils range in diameter from
1.5 inches to more than three feet.
Manufacturers and installers of com-
munications cable have known the
benefits of the Reelex package for
more than 30 years. By expanding
the scale of coil winding equipment,
Reelex has brought these same
benefits to products that were not
previously available.
