BENTHOWAVE INSTRUMENT INC. Acoustic Transducer & System
BII7720 Flush-Mounting Transducer: SONAR, NDT, AE Transducers.
BII7720 series transducers mount through a hole or counterbore hole
cut in the housing of SONAR/NDT/AE instruments, apparatus, vehicles
(or towed streamlined body), pipes, 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.
Transducers emit and receive conical beams, and are designed for use
as components in communication, positioning, navigation, fishery,
oceanography, Seafloor-mapping, Marine Animals research, NDT/AE,
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.
In NDT and AE applications (as immersion transducers or contact
transducers), the couplant (water, gel, grease, oils, commercial
couplant, and shear-wave couplant) is a necessary material to
provide efficient acoustic coupling between the transducer face and
the subject (piece under test).
