Free Flooded Ring (FFR) Transducer: Broadband, Deep Ocean & Low Frequency
BII7590 series transducers are low-frequency, broadband,
multi-resonance Free Flooded Ring (FFR) transducers characterized by
a low-quality factor (low Q). They provide a toroidal beam pattern
and operate over a frequency range of 1–30 kHz, making them suitable
for deep- and shallow-water acoustic communication as well as
low-frequency underwater sound generation.
The BII7590 series is not designed for
underwater acoustic detection. In a pulse-echo or transmit-receive
acoustic system, a BII759x transducer emits underwater sounds while
a separate hydrophone detects the returning echoes or ambient sound
sources.
