Flush-Mounting Transducer
BII-7720 Flush-Mounting Transducer
BII-7720 series transducers mount through a hole or counterbore hole
cut in
the housing of underwater instruments, apparatus, vehicles (or towed
streamlined body) or the wall of
swimming pools. The flush-mounting design of these
transducers minimizes surface discontinuity between the transducer
and the mounting wall (or hull), and allows for smooth water flow over the surfaces,
resulting in much
lower induced acoustic noise
(hydrodynamic noise, flow noise), less drag/resistance, avoidance of
accidental collision and better acoustic performance for the
underwater devices in motion such as towed fish/bodies, ROV/AUV/UUV, robots, etc...
Low-profile flush installation protrudes only 4.75mm outside the
housing with streamlined flange.
BII-7720 transducers emit and receive conical beams, and are
designed for use as components in communication/positioning,
navigation, fishery, oceanography, Seafloor-mapping, Marine Animals
research, etc....
The housing can be mounted on different materials
such as woods, plastics, fiber glass, ceramics and metals.
Marine sealants shall be used for sealing, bedding and installation.
The depth rating is limited by the sealing performance of the cured
marine sealants.
If you do not find any transducer suitable to your project, please
contact BII for bespoke designs on size, operating frequency, beam width,
mounting, etc...
