Piezohannas
8kHz-15kHz Cylindrical Underwater Acoustic Transducer Hydrophone
Conductance and Capacitance Curves
Measuring the conductance and capacitance curves of the transducer, and the resonant frequency should be (12.5±1.5) kHz.
Emission response and sound source level
Measure the transducer's response and sound source level within 8kHz~15kHz, among which the response at 12kHz is not lower than 130dB, and the sound source level is not lower than 185dB.
Horizontal directivity
Omnidirectional, measuring frequency 8kHz, 12kHz, 15kHz.
Vertical Directivity
Measure the vertical directivity of the transducer at 8kHz, 12kHz, and 15kHz, and the vertical opening angle at 12kHz is greater than 50°.
Hydrostatic pressure: 2MPa.
Conductance and Capacitance Curves
Transmitting voltage response (dB)
