General Catalog FISHERY PRODUCTS TECHNOLOGY FOR SUSTAINABLE FISHERIES

Transducers are the core of all of SIMRAD products. Naturally, a transducer is a part of an echosounder, an important part, but it is also in all of our other products too, sonars, sensors, hydrophones, etc. Because of this, SIMRAD designs and produces our own transducers in order to secure the best performance in all our products. In sonars, the transducer is built with up to 480 elements. All elements are designed and produced by SIMRAD. The production of a sonar transducer is complex and takes about 3 days to make. Each of the elements is then connected by cable to the transceiver. A...

Wireless trawl sensors communicate acoustically to the vessel and between sensors. To be able to do this, a transducer is needed to convert electrical signals into acoustic signals and vice versa. Small transducers in various frequencies are then placed inside the net sensor. Also, a hydrophone is placed under the vessel to communicate with the sensor. A hydrophone is only listening for echo, it is not transmitting anything. Wireless trawl sensors communicate acoustically to the vessel and between sensors. To be able to do this, a transducer is needed to convert electrical signals into...

SIMRAD Innovation, values and history

MORE THAN 70 YEARS OF INNOVATION SIMRAD's slogan is “Technology for sustainable fisheries” and we live by this slogan every day. SIMRAD believes that a sustainable fishery worldwide is the only right way to survive. By sustainable we mean a healthy take out of the world fish stocks as well as an efficient and profitable fishery for the fisherman. SIMRAD believes that technology is an important factor to achieve this. Products that we believe have contributed to a sustainable fishery are Echosounders with a Split Beam technology: this makes it possible to catch the right size fish. Catch...

The SIMRAD brand name is owned by the Kongsberg Group, a Norwegian technology company. The Kongsberg Group has a strong position in the maritime sector through its company Kongsberg Maritime (KM), where the SIMRAD brand name is sold from. KM manufactures products like Dynamic Positioning, MRUs (Motion Reference Units), high accuracy GPS positioning systems, Engine control systems, Bridge Navigation systems as well as all the SIMRAD products. • First SIMRAD Echosounder 1960 SIMRAD Innovation, values and history • First sonar with hydraulic hoist (SU) SIMRAD foundation • First sonar with...

HISTORY SIMRAD was founded in 1947 by Mr. Willy Simonsen. The name SIMRAD derives from “SIMonsen RADio” and, as the name indicates, it all started with radios. But this shortly developed into echosounders and sonars. Today, SIMRAD is recognized all over the world for premium performance products, manufacturing sonars, echosounders and net monitoring equipment. • First Omni with vertical and 90° tilt on sonar (SX202) • Full digital signal processing introduced • First composite sonar (SC90) • First trawl positioning system (ITI) • First echosounder with Split Beam (ES380) • CS90 first...

FISHFINDER TRANSDUCERS SIMRAD is one of the very few producers of transducers. The transducer is an important part of an echosounder's performance. A transducer is the combination of a microphone and a loudspeaker, all in SIMRAD Transducers one. The transducer is converting electrical energy into sound waves and vice versa. What you see on the echosounder screen is actually echoes from transmitted sound.

FROM ELECTRICITY TO SOUND The transducers' ability to convert electrical energy into sound depends on how it is built. The better it converts, the better the transducer is (and the echosounder performs better). There are several ways to make a transducer with different materials that can be used. Today, ceramics is the best material to use seen from a performance view. Other materials such as nickel or ferrite has a lower price but will not convert electrical energy as efficient as the more costly ceramic material. Also, the way the material has been used in the production also matters to...

SINGLE BEAM, SPLIT BEAM AND WIDEBAND TRANSDUCERS "We are at the forefront of performance through innovative design and a unique production technology" KJELL GJESTAD Value Chain Manager SIMRAD makes a wide specter of transducers and hydrophones to fit various echosounders frequency and configuration. We can divide the transducers in three categories: SINGLE BEAM TRANSDUCERS A Single Beam transducer will give you the normal information expected from an echosounder, like a school of fish, depth to bottom, separation of target from bottom, etc. It is still a must to have a high quality...
