18 KHz-34 KHz Cylindrical Communication Transducer Underwater Acoustic Transducer

Conductivity, capacitance

Measuring the conductivity and capacitance curves of the transducer in the frequency band of 1kHz to 50kHz, where the resonant frequency of the transducer should be in the range, and provide the resistance and capacitance data in the working frequency band.

Working frequency band

The working frequency band of the transducer is 18kHz-34kHz.

Transmitting response

Measuring the transmitting response in the working frequency band of the transducer, where the 25kHz is not less than 140dB.

Receiving sensitivity

Measuring the receiving sensitivity in the working frequency band of the transducer, where the 25kHz is not less than -190dB.

Horizontal directivity

Omnidirectional, measuring frequencies 18kHz, 25kHz, 34kHz.

Vertical directivity

Measuring the vertical directivity of the transducer at 18kHz, 25kHz, and 34kHz, where the opening angle at 25kHz should be not less than 200°.

Hydrostatic pressure test

The hydrostatic pressure resistance of the transducer should be not less than 3Mpa.

Cable

The transducer uses a two-core shielded cable with a cable length of 30m.
