We have heard trawl producers say that 80% of a trawl’s efficiency comes from the trawl doors working perfectly. We do not know exactly, but what we do know is that the significance is large: Door Distance sensors have, as we see it, been the most important sensors for most fishermen though 25 years, and now many call the Door Angle sensor the most important sensor Scanmar has developed.
The sensors are based on SS4 ScanSense technology:
- New sensor construction and newly developed plastic material
- 5 times larger battery capacity
- Programmable sending effect – multiplies the working time
- Fully charged in 2.5 hours
- Can be charged while on the doors
- Multifunctional – the sensors have several functions built in
- The functions can be used simultaneously or alternately
- New mounting kit; easy to weld on
- Simple to switch frequency when interference occurs
- Light diode shows when the sensor is transmitting
- Simple self test
The sensors that are included in the new Door sensor series are mounted parallel to the door’s horizontal and vertical axis. This makes the pockets simple to mount, while all sensors can be upgraded with an Angle function as well. The mounting is therefore important in order to receive correct angle measurements.
Functions included in the new SS4 Door sensor series are:
- Distance
- Angle
- Depth
- Tension
- Temperature
The sensors are delivered with one or more functions activated, and can, if desired, also be upgraded later by simply downloading a license.
