FX
3250/55
Automatic PICK
COUNTER
|
 |
The Automatic
PICK COUNTER is
used for fast,
convenient and
accurate
determination of
the thread
density of woven
fabrics and wire
meshes as well
as the loop
density of
knitted fabrics.
Two models of
the PICK COUNTER
are available:
FX 3250 with a
measuring range
of 8 through 300
threads/cm (20
through 762
threads/in).
FX 3255 with a
measuring range
of 8 through 74
threads/cm (20
through 188
threads/in).
The instrument
is equally suitable for
measurements in
the laboratory
and mobile
applications in
the production
environment.
Since the
instrument also
works at moving
test specimen,
measurements can
be taken
directly at the
running
production
machine or loom.
Its handy size
and its ability
to determine
even extremely
high thread
densities, make
the instrument
at state- of-
the-art
alternative to
the traditional
pick glass and
interference
template.

 FX 3250- MT Stand |
Function
For
testing,
the face
of the
instrument
is
placed
onto the
test
specimen.
After
manually
entering
the
search
range in
which
the test
result
is
expected
to fall,
the
start
button
is
pressed.
By means
of a
high
quality
lens
system a
narrow
line of
the test
specimen
is
projected
onto a
linear
CCD
array.
The
signal
from the
CCD
array is
processed
by a
micro
processor,
and
after
less
than a
second
the
average
thread
density
of the
test
specimen
is
digitally
displayed.
A
special
illumination
system
eliminates
the
interfering
effects
of
colors
and
patterns.
Because
of its
small
size and
light
weight
design
the
instrument
is
perfectly
suited
for
mobile
use.
For
stationary
operation
in the
laboratory
the
instrument
may be
mounted
to the
optional
FX 3250-
MT Stand.
The
model FX
3250 is
equipped
with a
RS 232
data
port.

The
instrument
can be
calibrated
and is
supplied
with an
ISO
conform
calibration
certificate.
Also
supplied
is a
calibration
card for
instantaneous
verification
of the
proper
function
and
calibration
as well
as for
recalibration
of the
instrument.

Evaluation
of the
test
results:
The
simplest
method
for
evaluation
of the
test
results
is
to read
the test
results
from the
digital
display,
to write
them
down and
to
evaluate
them
manually.
In order
to
eliminate
all
reading,
writing
and
calculating
tasks
and
related
errors,
the
model FX
3250 (only)
can be
connected
to a PC
with
printer
and
evaluation
software
or to
the
L 5130
Strip
Printer,
which
documents
the test
results,
including
statistical
analysis,
on a
narrow
strip of
paper. |

For
the FX 3250/FX
3255 Automatic
PICK COUNTER the
following
accessories are
available:
FX 3250-
KAB Data
cable for
transmission
of the
test
results
from the
FX 3250
PICK
COUNTER
into the
L 5130
Strip
Printer.
FX 3250- ARH
Alignment
aid
For
measurement
of
extremely
fine
test
specimens
with a
yarn
density
over
approximately
100
threads/cm
(250/in).
FX 3250-
GB Power
adapter
for a
line
voltage
of 90
through
264 V,
50
through
60 Hz,
with UK
connector.
