Flush-Mounting Hydrophone

BII-7110  Flush-Mounting Hydrophone

BII-7110 series hydrophones mount through a hole or counterbore hole cut in the housing of underwater 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.
The hydrophone 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.
For low flow noise omnidirectional hydrophone, please refer to BII-7010 Low Flow Noise Hydrophone.
