Sensor overview

This chapter provides a very short description of each sensor.

• Depth sensor - The Depth sensor provide information about

the current depth as well as the descending or ascending rate

related to the surface.

• Catch sensor - The Catch sensor provides information about

the amount of catch in the trawl. The sensor monitors the

opening of the meshes in the cod-end, and will activate once

the caught volume pulls the detector wire. To monitor the

filling rate, you are adviced to use minimum two sensors.

• Bottom Contact sensor - The Bottom Contact sensors

detects if a trawl is accidentally lifted off the seabed, or a

purse seine is touching the bottom.

• Rip sensor - The Rip sensor provides an immediate warning

when the net is ripped.

• Temperature sensor - Temperature sensors read and transmit

the ambient water temperature at the gear depth.

• Height sensor - The Height sensor contains s small echo

sounder to measure the current depth related to the seabed.

• Spread & Remote sensor - These sensor always work in

pairs, and they measure the distance betwen the trawl doors.

You can also use two Remote sensors if you run a twin trawl.

The use of separate communication channels for the individual

sensors allows you to use your sensors in the vincinity of other

vessels using PI or P S sensors. The communication channels can

be defined and/or changed onboard your vessel using a standard

computer and the P I Configurator utility.
