Installing the transducer(s)
The installation of the transducer (or transducers) is a key task for successful use of
the EK80 Wide band scientific echo sounder. Not only will you need to penetrate the
vessel’s hull, you must also to select a physical location for maximum performance
and minimum acoustic and electric noise.
Prerequisites
To get a full overview of the installation, you need all relevant vessel drawings. You also
need the drawings provided for each transducer.
Context
Necessary information for the installation of each transducer can be found in the end-user
documentation provided with the transducer.
End user manuals and source drawings (normally in AutoCad format) can be downloaded
from our website.

Procedure
1 Determine the physical location of the transducer.
The decision must be based on:
• The vessel drawings
• The shape and properties of the hull
Make sure that all possible considerations are made to reduce noise.
2 Based on the shape of the transducer housing, and the mounting devices available,
determine the installation method.
3 Design, manufacture and mount the necessary fairing, installation blister, keel box
and/or tank that is required to mount the transducer.
4 Design, manufacture and mount the steel conduit for the transducer cable.
5 Unpack the transducer from its transport crate.
6 Position the transducer under the mounting location.
7 Pull the transducer cable up through the steel conduit.
8 Tighten the packing nipple on the cable gland properly to avoid leaks.
9 Mount the transducer.
10 Seal the top of the steel conduit to prevent water leaks.
11 Connect the transducer cable to the Wide Band Transceiver (WBT).
12 If your vessel will operate in waters with a lot of marine growth, consider applying
a thin layer of anti-fouling paint to the transducer face.
