Thank you and we look forward to hearing from you!
This is your "eye" at the cod-end. With PI Catch sensors in use, you can easily monitor the filling 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 award winning, and the sensor's sensitivity is easily adjusted for trawls of all sizes.
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.
