Hydrophone and Phased Array

BII manufactures wide range of hydrophones (Underwater Microphones) and AE sensors for underwater and ultrasonic applications, and they are completely waterproof, corrosion-resistant and withstand high levels of salinity.

Low Noise: Lower than sea-state 0	Low Power: 40 to 350µA quiescent current for battery powered instruments
Miniature: Acoustic Aperture size Φ0.8mm	Broadband: Detect signal up to 3MHz
Sidelobe Suppression: ≤-30dB, Bespoke	Directivity: Omnidirectional and Directional, Custom-fit
Phased Array: Beamforming/Steering/Focusing	High Temperature: up to 198°C/390°F
Ocean Depth: up to 1000m	Projector: Hydrophones without preamp can be used as low power sound sources

Typical Applications
Underwater Sound Recording and Listening, Seismology	Ultrasonic (Ultrasound, AE, Nondestructive) Testing, Physical Acoustics
