Vibration Insensitive Hydrophone

BII-7090 Series Vibration Insensitive Hydrophone

When suspended from a ship or boat, buoy, or used in towed array, the hydrophone experiences a large movement and induced vibration resulting from surface waves, currents, hydrodynamic flow turbulence, cable movement, etc... BII-7090 series hydrophones cancel the translational acceleration in their axial direction and have low acceleration sensitivity in other directions. They can be deployed in these harsh fields and reduce spurious signals caused by induced vibration. A hydrophone with omnidirectional or toroidal response pattern has streamlined hemispherical dome which minimizes drag forces and hydrodynamic noises caused by the hydrophone in motion or the flow past the hydrophone. Optional mounting parts are available for installation on portable-mounting apparatus, submersibles, pipe, tank or vessel.
