aerOel has launched hwS.1 – handy
wire Scanner – a fully portable
optical micrometer for non-contact
measurement of wires, cables and other
similar products.
Developed using leD and CCD
technology, it uses two crossed linear
sensors to automatically compensate
positioning errors (patent pending).
thanks to a powerful single chip
microprocessor, the micrometer is
linearised and compensated to obtain
the maximum precision in the entire
field of measurement, regardless of an
accurate positioning of the wire.
the measurement is started by pressing
the trigger, which takes only a fraction
of a second. the display provides the
operator with interactive information
to place the wire in the useful
measurement area and displays the
measurement result.
all measurements are saved in the
memory of the scanner, associated
with the date, time and the number of
machine. through a uSB connection,
data can be downloaded to any PC. the
battery is charged via the uSB connector
with the supplied power supply. Battery
life, with the micrometer always active, is
approximately four hours.
the scanner has been designed to fit
into a special holder to be fixed on a
machine, and this contains an rFID tag
that identifies the machine, and which
is read by the instrument at the time of
measurement.
the support allows the easy and quick
placement of the scanner, and for the
measurement of moving products,
guaranteeing the maximum precision of
measurements.
It is therefore possible, mounting a
support on each line, to periodically
monitor the production of all machines
with just one micrometer.
the new micrometer hwS-1 enables
an intermediate solution that can
dramatically increase the frequency of
checks inside a coil, with the non-contact
technology making this possible.
with the measurement of products in
motion, there is no need to stop the
process or wait for the end of a reel. the
number of checks carried out inside a
coil can be significantly increased. with
small investment it allows you to equip
each machine with a specially designed
holder, and gives two additional
advantages:
• the positioning of the micrometer is
greatly facilitated
• at the time of reading the diameter,
the micrometer also reads the tag
contained in the fixture. this lets
you recognise and identify the
position or the machine where you
are measuring, and then combine
the stored results with respective
positions/machines
a single operator can monitor several
lines/machines. at the end of the shift
the stored data can be downloaded to a
PC for reports to be checked, and for it to
be printed.
In addition to this basic function, which
improves the sampling frequency, there
are a number of other uses such as the
set-up or the diagnosis of the process.
an example is the process of enamelling
copper wire: the modern lines start from
the copper wire drawing and produce
the finished product, applying and
drying several subsequent layers of
enamel, up to the finished wire which is
collected in reels.
even in the case in which the line is
fitted with a laser gauge to check the
final diameter before the reeling, the
handheld optical micrometer can be
useful in case problems arise, however
readily detected by the on-line gauge.
the next question is: where, at which
stage of the process the ‘anomaly’ has
occurred that led to the alarm.
