Deepwater Hydrophone Underwater Acoustic Transducer for Deepwater Depth
Technical Parameters：
model | YH-S/2000
|
resonant frequency | 40kHz |
working band | 20kHz一下 |
receiving sensitivity | ≥-200dB |
static capacitance | 5000pF |
directivity | Horizontal non-directional |
Vertical non-directional | |
working depth | 2000m,4000m,6000m,10000m |
cable specification | Φ5mm two core shielded cable |
Deep-water pressure-resistant structure design, can work in 2000m/4000m/6000m water depth.
Mixed application of multiple circuit structures ,to improve receiving sensitivity and static capacitance.
Completely built-in suspension structure to reduce the influence of structural vibration.
The hydrophone adopts a special pressure-resistant structure, and a series-parallel circuit structure is adopted between multiple ceramic elements to ensure the receiving sensitivity and static capacitance of the hydrophone under the premise of pressure resistance. This type of hydrophone has 2000 meters, 4000 meters, 6000 meters and ten thousand meters series. The electrical performance design and structure design of the transducer can be carried out according to user requirements.

Application case of underwater acoustic transducer
According to customer’ needs, we can design and produce piezoelectric ultrasonic transducers, underwater acoustic transducer ,ultrasonic probes and sensors of various frequencies with stable performance and high quality.
2. Calibration of Vector Hydrophones in Deep Water ,The maximum working depth can reach 3000m, which can be used for oil-filled linear array elements
3. The highest emission response of the stacked spherical acoustic transducer can reach 156dB, and the highest sound source level can reach 202dB, which is more than 6dB higher than ordinary spherical transducers of the same size.
4.single-crystal vector hydrophone transducer
Compared with piezoelectric ceramic transducers, the size of PIN-PMN-PT single crystal transmitting transducer is reduced by more than 1/3, the transmitting voltage response level is 2~10dB higher, the impedance bandwidth is about twice higher, and the -3dB bandwidth is about two times higher. Times; the receiving sensitivity is 3~5dB higher. The single crystal vector hydrophone has low motion self-noise, and the sensitivity is 4~6dB higher than the piezoelectric vector hydrophone of the same size.
5.Fixed installation vector hydrophone
Using the center column as the fixed base, the ceramic shearing working mode, the working frequency band is 100-5000Hz, the installation is simple, the performance is stable, and it can replace most vector hydrophones installed on various platforms.
The cone-shaped reflector is used to reflect the circumferentially radiated sound waves of the toroidal transducer to the end surface to work, and relatively stable acoustic radiation of the beam can be realized on the end surface.
