BENTHOWAVE INSTRUMENT INC. Acoustic Transducer & System
Low-Qm BII-7510 series are broadband high power communication transducers
with toroidal directivity pattern for uses in
voice and message channels underwater
especially in the horizontal plane, which is designed for analog
and digital communication underwater.
Carrier
frequencies of 3.5 to 360 kHz support long range and short range communication underwater. The
information can be exchanged from 10km away with low frequency
sounds.
Medium-Qm BII7510 series are miniature transducers with toroidal
directivity pattern for uses in underwater communication especially
in the horizontal plane, and in material study and medical research
as ultrasonic sources and sensors. Frequencies of 50 to 400 kHz and
sound levels of 180 to 190 dB μPa support short to long range sound
propagation in water, liquids, rubber-like material, and solids.
Their miniature sizes make them be suitable to be embedded in
materials.
