When is the trawl full?
This is your “eye” at
the cod-end. With PI
Catch sensors in use,
you can easily monitor
the fi lling rate and the
amount of catch in the
trawl. Save time and
fuel, haul in the trawl
at the right moment!
The design is rugged
and awardwinning, and
the sensor’s sensitivity
is easily adjustable for
trawls of all sizes.

Applications
(855-165190 / Rev.A / April 2005)
Some professionals claim that the Catch
sensor is the most important sensor on the
trawl. Why? Because it will tell you the
amount of catch in the trawl.
The sensor simply monitors the expansion of the
meshes in the cod-end. Once the volume caught
is enough to expand the meshes, they will pull the
detector wires and engage the sensor. The sensitivity
of the sensor can easily be adjusted, just extend the
detection rubber bands to span additional meshes.
To monitor the filling rate, we recommend that
you use minimum two sensors. Place the first sensor
at the far end of the cod-end, it will tell you that the
trawl is actually fishing. Place the second sensor
closer to the trawl opening. Once the trawl is filled to
the chosen location, the sensor is engaged, and you
know that it is time to haul.
Use the PI Catch sensor to adjust the catch volume
according to the production capacity, check that the
trawl is fishing, adjust the caught volume to secure
quality, and minimize the towing time to save fuel.
These are only a few of the reasons why this sensor
is considered to be so important.
