160Khz Spherical Transmitting Receiving Transducer Spherical Underwater Acoustic Transducer
We independently developed acoustic transducer products cover a full range of hydrophones, transmitting transducers, transceiver transducers, sonar array transducers and ultrasonic transducers, covering overflow rings, flextensional and curved discs. and composite materials, etc., achieving full coverage from low to medium frequency to high frequency, from shallow water to 10,000-meter water depth, and can be widely used for listening and homing detection, communication networking, positioning and navigation, seabed surveying and mapping, forward-looking side scanning, industrial and medical ultrasound and other types of acoustic equipment.
Measurement content:
1.1.1. Voltage Transmitting response and sound source level
Measuring the voltage response and sound source level of the transducer in the frequency band of 25kHz-125kHz, where the resonant frequency response is not less than 145dB and the sound source level is not less than 192dB.
1.2. Receiving sensitivity
Measuring the receiving sensitivity of the transducer in the frequency band of 25kHz-125kHz, where the resonant frequency response is not less than -205dB.
1.3. Directivity
Measure the horizontal and vertical directivity of the transducer at 50kHz.
1.4. Hydrostatic pressure
Hydrostatic pressure: 3MPa.
2. Measurement data
There are 2 transducers, 202501# and 202502#, and their measurement data are as follows.
Hydrostatic pressure resistance
The hydrophone should be able to withstand 2Mpa hydrostatic pressure test.
