| | | These two sensors always work in pairs. They are used to monitor the physical distance between the trawl doors during bottom and pelagic trawling. 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 marine rope. The Spread sensor communicates with the Remote sensor using a special transverse communication link. By means of this link it measures the excact 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, | | |
