PI sensor information The PI sensors provide information about the filling rate of fish in the cod end, door spread, etc. FS70 TRAWL SENSOR/VERTICAL SOUNDERPI DEPTH SENSOR (back up)PI CATCH SENSORS The Simrad FS70 full screen presentation in a polarsounder mode indicates the position of the trawl close to the bottom and the opening of the net by displaying the Cursor 1 and 2. In addition, the sounder display provides an accurate depth of the bottom and the foot rope. The operator can monitor up to 4 catch indicators, indicating the amount of fish being caught by the trawl and the time when the sensors where activated. The Simrad FS70 200kHz echo-sounder provides a real time picture of the trawl opening and position relative to the bottom. In addition to the high resolution sounder, the operator can control the descent of the trawl during the set by monitoring the position of the foot rope and the bottom. PI BOTTOM CONTACT OR RIP SENSORS FS THIRD WIRE TELEMETRY LINKPI HYDROPHONES (acoustic link) PI SPREAD SENSORS FS70 Trawl unit The FS70 trawl housing unit is designed for the harshest environments and for withstanding the extreme forces encountered when shooting a trawl. However, it is easy to handle and the Hyper yellow colour makes it easy to see even in the dark. NEW FLEXIBLE TRAWL SONAR SYSTEM Simrad FS70 sounder display mode. Simrad FS70 full screen display mode. SIMRAD SYSTEM FS THE NEW TRAWL SONAR PLATFORM COMBINES THE BEST OF TWO WORLDS The new Simrad FS Trawl system provides the full picture by utilizing the ultimate FS third wire system with PI sensors integration. This sophisticated solution enables the fisherman to have full control of any type of trawl fishery. The system provide real-time images from the trawl sonar head and the data from the PI sensors to the bridge, thus maximizing the quality of the catch and increasing effeciency at sea. Simrad PI sensor range and monitors from 6” to 15”. A major benefit of the third wire integrted with PI sensors is to prevent loss of communication with the trawl as the vessel is changing course or in heavy sea conditions. The perfect back up By installing a PI cabinet and hydrophone, you have a complete back up system for catch indicators and other sensors. It is now possible to get trawl height, door spread, catch and depth information from the wireless sensors by implementing the receiver from the wireless PI system into the third wire FS system. In addition all the data from the wireless sensors can be received wireless by the vessel making it the ulti- mate back up system if the third wire breaks.
