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 ES120-7CD SIMRAD ES120-7CD The purpose of this manual is the provide the basic information required to install the Simrad ES120-7CD Split-beam transducer.
Towed body design TOWED BODY DESIGN A towed body used to hold the 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 ES120-7CD 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 ES120-7CD Example 1: 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 2: 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 ES120-7CD Example 3: Dual transducer arrangement 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. 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. Transport protection Some transducers are delivered with a cover plate on the face for protection during transport.

Transducer handling and maintenance Introduction to Emuge self-locking threads Emuge self-lock is a tap design with an integrated locking feature. Standard metric bolts 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). The Emuge self-lock bolts withstand vibrations better than standard (metric) threads, because the thread contact stops the sideways movement.
Simrad ES120-7CD • Economically efficient locking system, no additional components are necessary • Undiminished holding power even under dynamic stress • Repeated loosening and re-tightening without loss of function • Internal threads can be produced with Emuge taps, cold forming taps or thread mills • Larger thread hole diameters, i.e.
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. 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. Threads Drill diameter for threads Part.
