Free-Flooded Ring (FFRs) Model PyFFR-16-32-Oil
Free-Flooded Ring (FFRs) Model PyFFR-16-32-Oil
This transducer is based on the standard Free-Flooded Ring technology. It presents several advantages: broadband (typically 1 octave), unlimited immersion depth, and hemispherical directivity. The transducers are ideal for use in a range of applications such as underwater communication, telemetry and acoustic positioning.
