Hydrophone and Ultrasonic Preamplifier

BII's low noise low power preamplifiers (amplifiers) have built-in filters and their gains are fixed or programmable with digital and analog control. These preamplifiers (amplifiers) are custom-fit for use in broadband (wideband) underwater SONAR, ultrasonic (Ultrasound, NDT, AE) system and Measurement of ferroelectric and piezoelectric materials.

Typical Applications
Hydrophone, SONAR, Underwater Communication	Ultrasonic (Ultrasound, AE, NDT) Testing, Material Characterization
