PI Spread Sensor

Used on bottom and pelagic trawls the Spread and Remote sensors provide crucial information about your trawl behaviour. This dynamic duo tells you the exact distance between the trawl doors.

Information from the sensor

The PI Spread and PI Remote sensors always work in pairs. They are used to monitor the physical distance between the trawl doors during bottom and pelagic trawling.

Applications

Use a Spread sensor on the port door and a Remote sensor on the starboard door. Both sensors are normally mounted in special adapters, but you may also attached them to the wing-end or warp using snap hooks or rope.

The Spread sensor communicates with the Remote sensor using a special transverse communication link. By means of this link it measures the exact distance (maximum 350 meters) between the two sensors. The information is is transmitted to the vessel by the Spread sensor.

As you already know, correct door spread is important in order to obtain the correct sweep-angle, as this ensures optimal trawl performance. Door behavior and stability during shooting and towing is also monitored by these sensors. Many regard this pair of sensors one of the most important sensors to obtain efficient trawling.

Installation

In order to use these sensors, you must mount them on the trawl doors.
