Installation manual

Ways of mounting the transducer
Acoustic window
Vessels operating in arctic waters need special attention on
transducer installation. Floating blocks of ice may damage even
a flush mounted transducer face. For this situation Simrad offers
arctic tanks in different sizes.
Mounting and clamping rings
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 inside the
steel tank, while the clamping ring fits around the edge of the
transducer body. Bolts through the clamping ring into the
mounting ring will then secure the transducer between them.
Note that several transducers use direction guides to allow correct
mounting.
Smooth surface
Mounting screws or bolts must not be extruding from the
acoustic window. Ensure t hat the surface of the window, the hull
plating and putty around the transducer is as even and smooth as
possible. Obstructions on these surfaces will create problems
with turbulant flow.
Horizontal support bar
Large diameter transducers must be fitted with a horizontal
support bar. This bar can be secured to the mounting ring using
threaded rods.
