HOW TO INSTALL THE TRANSDUCER

Transducer installation in blister

164986/D
There are many different ways to mount the transducer. These
are the recommended methods to mount a circular transducer.
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.
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. 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. Make sure that the
surface of the transducer face, the installation hardware used to
mount it, the hull plating and the putty around the transducer is
as even and smooth as possible. Obstructions on these surfaces
will create problems with turbulent flow.
