    Simrad ES120-7C Simrad ES120-7C The Simrad ES120-7C is a split beam composite transducer designed for fishery and underwater science applications. The beamwidth is 7 degrees at its nominal operational frequency. The transducer offers a large bandwidth. This provides a fine range resolution, which is important for single fish detection and target strength measurements.

    Cleaning and painting the transducer face During normal use, the transducer is subjected to biological fouling. If this marine growth is excessive, it will reduce the performance of the ES120-7C. The transducer has not been designed with any protection against biological fouling.

  • Page 17: Approved Anti-Fouling Paints

    Because some paint types may be aggressive to the polyurethane in the transducer, consult our list of approved paints. The list can also be found on http://www.simrad.com. Observe the relevant instructions and safety information provided by the paint manufacturer.

  • Page 18: Inspecting And Cleaning The Transducer Face

    Painting the transducer face, page 18 Inspecting and cleaning the transducer face Marine growth (biological fouling) on the transducer face reduces the ES120-7C performance. For this reason, it is important to keep the transducer face clean. Every time your vessel is in dry dock, you must remove the marine growth. At the same time, you must inspect the transducer closely for physical damage.
  • Page 19 During normal use, the transducer is subjected to biological fouling. If this marine growth is excessive, it will reduce the performance of the ES120-7C. Whenever opportunity arise, typically when the vessel is dry-docked, the transducer face must be cleaned for shells and other marine growth.

  • Page 20: Painting The Transducer Face

    Do a thorough visual inspection of the transducer. Check for dents, scratches, holes or other damage to the surface. If you suspect damage, take a high resolution photo. Contact your dealer or the Simrad support organization for advice. If necessary, apply anti-fouling paint as described in the dedicated procedure.

    Simrad ES120-7C Installation Manual Transducer installation in a blister In order to install a transducer with a circular housing, one recommended installation method is by means of a blister. The blister must be designed and manufactured by the installation shipyard to fit the transducer, as well as the vessel’s size and hull shape. The transducer may be added to an already existing blister that also holds other flush mounted transducers.

The distance from the keel is a trade off between a close distance giving a turbulent flow of water in a narrow passage, and a large distance bringing the transducer higher up, and therefore more affected by the vessel roll.

  • Page 63: About Cable Glands

    Note Simrad strongly recommends that a length of conduit is fitted around transducer cable glands made of steel or bronze and extended over the water-line inside the vessel. This precaution reduces the danger of flooding in the event of gland failure and transducers installed in this manner are also easier to replace.

  • Page 73: Introduction To Transducer Location

    Mount the transducer deep In order to achieve the best possible ES120-7C performance, mount the transducer as deep as possible under the vessel’s hull. There are several reasons for this recommendation.

  • Page 74: Avoid Protruding Objects Near The Transducer

    Simrad ES120-7C Installation Manual Slamming Slamming happens if the vessel hull climbs out of the water in heavy seas. The force of the water when the hull falls down may push the transducer up, and may cause damage both to the transducer and to its mounting. This is especially important for low frequency transducers with large faces.

  • Page 75: Keep The Transducer Far Away From The Propellers

    The propulsion propellers is the dominant noise source on most vessels. The noise is easily transmitted through the water. This noise may often reduce the overall performance of your ES120-7C. The transducer must be installed as far away from the propellers as possible. The best positions are therefore on the fore part of the hull.

  • Page 76: Mount The Transducer At A Safe Distance From Bow Thruster(S)

    When in operation, the noise and cavitation bubbles created by the thruster may make your ES120-7C Transducer useless, almost no matter where the transducer is installed. When the bow thrusters are not in operation, the tunnel creates turbulence. If your vessel is pitching, the tunnel may be filled with air or aerated water in the upper position and release this in the lower position.

  • Page 77: Summary And General Recommendations

    Where to install the transducer Summary and general recommendations Some of the installation guidelines provided for transducer location may be conflicting. For this reason, each vessel must be treated individually in order to find the best compromise. In general, the most important factor is to avoid air bubbles in front of the transducer face. For this reason, the recommended transducer location is normally in the fore part of the hull, well ahead of the noise created by the bow wave.
  • Page 78 Simrad ES120-7C Installation Manual If the vessel hull has a bulbous bow, this may well be a good transducer location, but also in this case the flow pattern of the aerated water must be taken into consideration. The foremost part of the bulb is often a good location.
