Page 9: Where To Mount The Transducer
Where to mount the transducer Where to mount the transducer A single answer to the question where to locate the transducer cannot be given. It depends very much on the vessel’s construction, how the hull is shaped and how the water runs along the hull. - Page 10 Simrad ES38-12 that the hull area around the transducer face is as smooth and level as possible. Even traces of sealing compound, sharp edges, protruding bolts or bolt holes without filling compound will create noise. Mount the transducer at the forward part of the hull to minimise the effects from...
- Page 11 Where to mount the transducer Mount the transducer far away from the propellers The propulsion propeller is the dominant noise source on most fishing vessels, research vessels, merchant vessels and pleasure crafts. The noise is transmitted through the sea water. For this reason, the transducer should be placed far away from the propeller, which means on the fore part of the hull.
- Page 12 Simrad ES38-12 Figure 2 General recommendation for transducer location Transducer Inclination angle Hull length at water line Maximum 1/3 of the hull length at water line (C) If the vessel hull has a bulbous bow, this may well be a good transducer location, but also here must be taken into consideration the flow pattern of the aerated water.

Page 13: How To Install The Transducer
How to install the transducer How to install the transducer There are many different ways to mount the transducer. These are the recommended methods to mount a large and medium sized transducer using a mounting plate. Topics • Transducer installation in blister on page 11 •... -
Page 14: Example: Large Circular Transducer
Simrad ES38-12 Example: Large circular transducer The illustration below shows a typical transducer blister designed for a large transducer. Note that due to the physical size of the transducer, a U-shaped support bar (E) is used to support the transducer. The purpose of this support is to prevent the transducer from being pushed up into the blister in heavy seas. -

Page 16: Common Guidelines
Simrad ES38-12 Common guidelines The best performance is obtained with a blister height of 40 cm or more. A streamlined shape and rounded edges reduce the flow noise. A vertical leading edge or front will guide the aerated water to the sides of the blister. The orientation of the blister should follow the water flow. -

Page 19: Example: Flush Mounting In A Steel Tank
Vessels operating in arctic waters need special attention on transducer installation. Floating blocks of ice may damage even a flush mounted transducer face. For this situation Simrad offers arctic tanks in different sizes. Use mounting plate whenever provided Certain transducers may be provided with a mounting plate, or with drawings to allow for local production of this. -
Page 20: Example: Acoustic Window
The best result is obtained when the distance is half a wavelength. Consult Simrad for advice. In addition to the loss, the beam pattern is degraded, because a larger area of the hull is set into vibrations. -
Page 21: Example: Mounting Inside The Hull
How to install the transducer Make sure that the surface of the transducer face, the installation hardware used to mount it, the hull plating and the putty around the transducer is as even and smooth as possible. Obstructions on these surfaces will create problems with turbulent flow. Example: Mounting inside the hull Figure 12 Mounting inside the hull Steel tank... -

Topics • General requirements on page 21 • Installation in a towed body on page 22 General requirements Smooth surface is important Mounting screws or bolts must not be extruding from the transducer or the area immediately around it. -
Page 24: Installation In A Towed Body
Simrad ES38-12 Installation in a towed body Transducers designed to withstand large water pressure are provided for use in towed bodies. The recommended installation method is through the hull plating hull using a mounting plate, or with mounting and clamping rings. The installation arrangement on the towed body must be designed by the manufacturer of the towed body to fit its shape and characteristics. -

Page 31: Introduction To Emuge Self-Locking Threads
Transducer handling and maintenance Introduction to Emuge self-locking threads is a tap design with an integrated locking feature. Standard metric bolts Emuge self-lock are used. The internal thread provides a self-locking connection, which can be used repeatedly. It is not necessary to involve a secondary locking device (e.g. chemical, nylon or mechanical). -
Page 32: Drawing Standard
Note: The self-lock threads marked with SL* must be made in accordance with procedure 842–202125. Drill diameters for threads differ from standard. Self-lock taps can be supplied by Simrad. Taps and gauges The pretension locking thread self–lock (taps) from manufacturer must be used. -

Page 34: Transducer Cable Splicing
If you need to cut or lengthen the transducer cable, you must splice it correctly. The cable between the junction box and the transceiver must then be supplied by Simrad, and this must be the same type as used on the transducer(s). To splice the cable, use a metal junction box with EMC cable glands and a terminal block. -
