Types of Underwater Acoustic Transducer
1.Low frequency, deep water, high power transducer
Low-frequency transmitting transducer series: There are various types of flexural transducers, slotted circular tube transducers, slat bending transducers, combined bending disc transducers, etc. The minimum operating frequency has been as low as 20Hz;
Deep-water transducer series: there are three types of products: overflow type, oil-filled pressure balance type and self-supporting pressure type, the maximum pressure resistance has reached 80MPa;
High-power transmitting transducer series: The sound source level can reach more than 207dB near 350Hz.
2. Mosaic ring transducer
The company has the ability to design and manufacture mosaic rings with a diameter of 30mm～800mm, the frequency can cover 0.5kHz～50kHz, the highest emission sound source level of a single transducer can reach 202dB, and the effective working frequency band can reach more than 2 octave frequencies. Its structural form Mainly divided into air-backed type and overflow type, the working depth can reach 500m and 6km respectively.
3. Line array
The company has the ability to design and manufacture oil-filled linear arrays, cable linear arrays, and rigid linear arrays. The oil-filled array can realize the oil-filled linear array with the smallest outer diameter of 20mm, and the longest single array segment can reach 80m.
4. Spherical transducer
The company has mature design and production technology for spherical transducers. At present, it has formed a complete series of spherical transducers with a diameter of 20mm to 166mm after packaging; the transmission coverage frequency is 3kHz to 150kHz; the reception coverage frequency is from 5Hz to 100kHz+; the working depth is the highest Up to 5km or more.
5. Vector hydrophone
The company is the first company in the industry to develop vector hydrophones and its engineering applications. The differential pressure vector hydrophones and co-vibration vector hydrophones developed are stable and reliable. The working frequency band can cover 5Hz~120kHz, and the maximum working depth can be Up to 3000m. In order to improve the suitability of the co-vibration vector hydrophone, our company has conducted in-depth research on the installation method, waterproof current impact and suspension mode, etc., and realized fixed installation vector hydrophone, oil-filled structure and free suspension, etc. A variety of results, and has the design and manufacturing capabilities of vector hydrophone line arrays and towed arrays.
