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 ES333-7C noise at certain frequencies. Do not place an echo sounder transducer in the vicinity of such objects, and especially not close behind them. For the same reason, it is very important that the hull area around the transducer face is as smooth and level as possible.
- Page 11 Where to mount the transducer and flat bottom, with a rising angle less than around 13 degrees, is prone to giving air problems for the transducer. In any case a transducer location in the forward part of the hull is preferred in order to minimise the influence of the boundary layer.
- Page 12 Simrad ES333-7C beam angle your transducer has, the smaller the inclination angle can be. Ensure that you do not mount the transducer with a negative inclination angle. This may cause turbulence under the transducer face, and reduced echo sounder performance.
- Page 13 Where to mount the transducer 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. Often the foremost part of the bulb is preferable.

Page 14: How To Install The Transducer
Simrad ES333-7C HOW TO INSTALL THE TRANSDUCER There are many different ways to mount the transducer. These are the recommended methods to mount a circular transducer. Transducer installation in blister With a transducer with circular housing, one recommended installation method is by using a blister. The transducer blister must be designed and manufactured by the installation shipyard to fit the vessel’s size and hull shape. - Page 15 How to install the transducer Example: Large 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.
- Page 16 Simrad ES333-7C Example: Small transducer The illustration below shows a typical transducer blister designed for a small transducer. The same blister design principles as for a large transducer apply. Streamlined blister Mounting ring Clamping ring Guide Air outlet Forward Transducer cable Note that the transducer cable must be provided with a cable loop inside the blister.
- Page 17 How to install the transducer Example: Medium sized transducer without clamping ring The illustration below shows a transducer blister designed for a medium sized transducers. The same blister design principles apply. Note that the transducer is mounted without a clamping ring, which makes it necessary to use a different mounting ring design.
- Page 18 Simrad ES333-7C 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: Transducer Installation In Box Keel
How to install the transducer Physical location The blister is placed on one of the sides of the hull, and 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 also more affected by vessel roll. - Page 20 Simrad ES333-7C the transducer body. Bolts through the clamping ring into the mounting ring will secure the transducer between them. Note that several transducers use direction guides to allow correct mounting. Smooth surface is important Mounting screws or bolts must not be extruding from the transducer or the area immediately around it.

Page 21: Transducer Flush Mounted In A Steel Tank
How to install the transducer Transducer flush mounted in a steel tank Flush mounting is used on very large vessels with a hull so deep that no air bubbles are found below the hull, and on vessels operating in shallow harbours or waters, where a protruding blister can not be accepted. -

Transducer with acoustic window 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 and clamping rings whenever... -
Page 23: Transducer Mounted Inside The Hull
The loss varies with the distance between transducer face and the hull. 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 24 Simrad ES333-7C Use mounting and clamping rings whenever provided Circular transducers may be provided with mounting and clamping rings, or with drawings to allow for local production of these. The mounting ring is welded to the hole prepared for the transducer, while the clamping ring fits around the edge of the transducer body.

Page 25: Transducer Mounted On A Drop Keel
How to install the transducer Transducer mounted on a drop keel The use of a drop keel with the purpose of stabilising the vessel is well known. A drop keel is also a superior platform for echo sounder transducers. Such instrument keels have been built, mainly on research vessels, often protruding as far as three meters below the hull. -
Page 26: Retractable Transducer
Simrad ES333-7C Retractable transducer Hull units allowing the transducer to be lowered and hoisted are commonly used for horizontal looking sonars. When not in use, the transducer is retracted into a trunk. The retractable hull unit is more expensive than a blister, but on vessels with a hull where it is difficult or impossible to install a blister, it may still be worth while. -
Page 27: Transducer Cable Glands And Splicing
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 28: Cable Gland For Steel Hulls
The cable gland kit includes all of the necessary parts needed to install the unit except screws. Simrad recommends that a one inch steel conduit (that the transducer cable will be run through) with an inside threaded diameter of three-quarter inches is welded to the gland’s stuffing tube. -
Page 29: Cable Gland For Wooden And Grp Hulls
The cable gland kit includes all of the necessary parts needed to install the unit except screws. Simrad recommends that a one inch steel conduit (that the transducer cable will be run through) with an inside threaded diameter of three-quarter inches is attached to the gland’s packing nipple. -
Page 30: Cable Glands For Small Hulls
Simrad ES333-7C Cable glands for small hulls This cable glands made of plastic is designed for those smaller vessels that do not need to be classified. Packing nut (bronze). Make sure that you do not to damage the transducer cable by tightening the packing nut too hard! -
Page 31: 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. -
Page 32: Steel Conduit
Simrad ES333-7C STEEL CONDUIT Why use steel conduits? It is strongly recommended to lay a steel conduit from the transducer’s cable gland to the echo sounder transceiver, and to pull the transducer cable through this conduit. There are several reasons for this. -
Page 33: Transducer Handling And Maintenance
An anti-fouling paint may be applied to the transducer face. Because some paint types may be aggressive to the polyurethane in the transducer face, please consult Simrad’s list of approved paints. See Approved anti-fouling paints on page 31. Cleaning the transducer face... -

The bolts withstand Emuge self-lock vibrations better than standard (metric) threads, because the thread contact stops the sideways movement. The special design of the internal thread profile also provides a more even distribution of the tightening stress over the whole thread length.
