Power Amplifier: SONAR, NDT, HIFU

BII's power amplifiers are designed to drive underwater and ultrasonic transducers from 10Hz to 10MHz: SONAR, NDT, HIFU and Ultrasonic Power Transducers. Linear, switch mode (Class D or Switching) and waterproof (IP68) power amplifiers are available. They can also be used to provide low and/or high electric field (with BII-6000 step-up transformer) for dielectric materials characterizations such as P/E or D/E hysteresis, dielectric constant and loss, and their field-level and frequency dependence (Measurement of ferroelectric and piezoelectric materials).
BII-5110 series switching amplifiers have valuable features of high power capability, low power consumption, high efficiency, wide bandwidth and small size for battery-powered acoustic instruments such as sonobuoy, underwater pinger, transponder, acoustic release, etc...

Typical Applications
Subbottom Profiler, Sea-floor Mapping, Depth Sounder.	Ultrasonic (NDT) Testing, Dielectric Material Characterization.
Speedometer, Fishing Finding, Navigation, Acoustic Positioning.	Sonic Processing, Process Control, Cavitation, HIFU.
Underwater Communication, Telemetry, Acoustic Beacons, Remote Control.	Marine Animal Acoustics, Bioacoustics, Sound Playback.

Switch Mode Operation: Input signal of the PA is pulse or square signals with TTL/CMOS level or 2Vpp to 5Vpp.

Source Level of a transducer is calculated with efficiency 0.7 in water. DI is Directivity Index of the transducer, in dB.

Refer to Acoustic Components and System: Drive Transducers with Nominal Impedance 50/60/70/75/100Ω.
