SEAM DETECTOR
Hall sensor for fabric dyeing machines
The Seam detector uses the Hall
Effect, which means the sensitivity is
not affected by machine speed or the
stainless wall of the machine. It can
be easily installed on the outside of
the machine.
The Seam detector is designed for
use on most types of fabric dyeing
machines. A sensor unit is mounted
on the outside of the machine at a
point near to where the fabric
passes. A magnet is sewn into the
fabric seam and this triggers the
sensor when it passes. A relay is
activated in a separate amplifier unit
for about 2 seconds, and the volt
free changeover contact on this relay
may be used as required.
Typical uses include stopping the
machine when the seam is found for
unloading, or checking that the
fabric is circulating within a particular
time frame.

• Sensitivity adjustment
The sensitivity of the unit can be
adjusted, using a potentiometer.
At maximum sensitivity the passing
of the supplied magnet, when
correctly orientated, will be detected
at a distance of at least 250mm.
• Use of dual sensors:
Only in case of very wide tubes: If
the fabric can move more than
150mm from side to side it may be
advisable to use two sensors per
rope.
• Hall sensor - can be mounted
outside the machine.
• Can be used on most types of
fabric dyeing machines.
• The system comprises 3 parts:
amplifier, sensor head with 10
meters of cable, magnet for
sewing into the fabric seam.
• Amplifier can be mounted within
the control panel.
• Typical uses: stopping the machine
when the seam is found for
unloading, checking that the fabric is
circulating within a particular time
frame.
• The detector should be mounted on
a stainless bracket. This allows
enough cooling to keep the unit
well within operating temperature,
even at machine temperatures
higher than 125°C.
