Transducer installation in keel box
Vessels with a keel box may use this for transducer installation. The keel is already the
deepest part of the vessel. If the keel is too narrow to accommodate the transducer, it
can be widened, either symmetrically or to one side only. If the keel width is increased
to one side only, the installation principle could also be regarded as a blister merged
into the keel.

Using the clamping and
the mounting ring
This circular transducer
is designed to be mounted using a clamping and a mounting ring. The mounting ring is
welded to the hole prepared for the transducer. Bolts through the clamping ring into the
mounting ring secure the transducer in place.
Note
The transducer uses a direction guide to secure correct mounting. Observe the additional
"Forward" arrow on the transducer body.
Suitable mounting and clamping rings can be provided by Kongsberg Maritime. The
drawings are available for local manufacturing. The drawing (normally in AutoCad
format) can be downloaded from our website.

Smooth surface is important
Make sure that the surface of the transducer face, as well as the plating and putty around
the transducer is as even and smooth as possible. Obstructions on these surfaces will
create problems with turbulent flow, and may cause noise.
