300 Hz-10 kHz laagfrequente zendtransducer Akoestische onderwatertransducer
1.1.1. Werkende frequentieband
De werkfrequentieband van de transducer is 300 Hz ~ 10 kHz.
1.2. Weerstand en capaciteit
Biedt weerstands- en capaciteitsparameters binnen de werkfrequentieband van de transducer.
1.3. Uitgezonden geluidsbronniveau

Het geluidsbronniveau in de frequentieband 1 kHz~2 kHz bedraagt niet minder dan 170 dB. Het geluidsbronniveau in de frequentieband 2 kHz~10 kHz is niet lager dan 180 dB.
1.4. Horizontale directiviteit
Omnidirectioneel, meetfrequenties 300 Hz, 1 kHz, 2 kHz, 5 kHz, 10 kHz.
1.5. Verticale richtingsgevoeligheid
De verticale openingshoek in de frequentieband 300 kHz ~ 5 kHz is niet minder dan 85 ° en de meetfrequentie is 300 Hz, 1 kHz, 2 kHz, 5 kHz en 10 kHz.
1.6. Hydrostatische druk: 0,5 MPa.
