Transducer Installation In Blister - Simrad ES70 - INSTALLATION REV A Installation Manual

Example: Streamlined transducer on hull with flat bottom
If the vessel's hull is flat you do not need a fairing. The transducer is then be bolted
directly to the hull using two bronze or stainless steel bolts (I) and a cable bushing. Note
that the cable bushing must be mounted with proper gaskets (4) under and over the hull,
as well as sealing compound (J) around its body. Also, fill the bolt holes with a filling
compound to ensure a smooth transducer surface.

Transducer installation in blister

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.
