Simrad ES200-7C
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.
Example: Mounting inside the hull
The transducer shown in the figure below is mounted inside the
hull. The tank is filled with oil.
