About this manual ABOUT THIS MANUAL Purpose The purpose of this installation manual is to provide generic descriptions and illustrations allowing the reader to understand the basic principles for echo sounder transducer installation. About the information provided in this document The information in this document must be regarded as general guidelines and recommendations only. The installation shipyard must design and manufacture installation hardware to fit each individual transducer and vessel.
Simrad ES333-7CD SIMRAD ES333-7CD The purpose of this manual is the provide the basic information required to install the Simrad ES333-7CD Split-beam transducer.
Towed body design TOWED BODY DESIGN The towed body used to hold the ES333-7CD Split-beam transducer is not provided by Simrad. The design and manufacturing of such a body must be made by your own organisation, or by a third party you wish to engage to do this. During the design phase, the following considerations must be made.
Simrad ES333-7CD the sound energy, and may in worst cases block the sound transmission totally. Therefore, design the towed body so that it can operate in deep water. Caution Observe the maximum operational depth of the transducer. Do not exceed this limitation. Do not allow the towed body to hit the sea bed. This may inflict permanent damage to the transducer(s).
How to install the transducer HOW TO INSTALL THE TRANSDUCER Installation on 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 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.
Simrad ES333-7CD Example: Installation of small transducer The illustration below shows the installation principle of a small circular transducer using clamping and mounting rings.
How to install the transducer Example: Installation of medium and large transducers The illustration below shows the installation principle of a medium or large transducers. Note that a clamping ring is not required, as the transducer body is shaped to facilitate this function.
Simrad ES333-7CD Example: Dual transducer arrangement in towed body The illustration below shows a typical through the hull installation of small and large circular transducers on a towed body.
Transducer handling and maintenance TRANSDUCER HANDLING AND MAINTENANCE You MUST observe the following rules for handling, maintenance and painting. Topics • Rules for transducer handling on page 13 • Approved anti-fouling paints on page 13 • Using self-locking taps on page 14 Rules for transducer handling Note Do not lift the transducer by the cable. Do not expose the transducer to direct sunlight. Do not expose the transducer to excessive heat.

Transducer handling and maintenance necessary to involve a secondary locking device (e.g. chemical, nylon or mechanical). The Emuge self-lock bolts withstand 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. The assembly is just as easy as with a normal (metric) thread.
Simrad ES333-7CD • Internal threads can be produced with Emuge taps, cold forming taps or thread mills • Larger thread hole diameters, i.e. increased tool life for threading tools • Larger tolerances for thread hole diameters Drawing standard Whenever self-locking threads are required, this is shown on the technical drawing. In the case of tapping through holes, the arrow at the end of the center line illustrates the screw-in direction of the bolt.
Transducer handling and maintenance Figure 7 Example of use (CD017020C) Note In the case of tapping through holes it is important that the profile of the Emuge self-lock threads is in the correct direction compared with the entering direction of the bolt. Gauge Use Emuge self-lock gauges. Note that the gauge must be used in the correct direction. Self-lock taps provided by Simrad The following self-lock taps are on stock at Simrad, and can be ordered from us.
Simrad ES333-7CD 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. The terminal block must provide solid fastening of the cable ends as well as sufficient insulation between the wires.
Steel conduit STEEL CONDUIT Why use steel conduits with a towed body? It is strongly recommended to lay a steel conduit from the connection point of the tow cable to the echo sounder transceiver, and to pull the transducer cable through this conduit. There are several reasons for this. • It will make it easier at a later stage to replace the cable. • Noise and interference from other electrical equipment is greatly reduced.
