DPFS6KⅠ
DPFS6KⅠ
6Khz Low Frequency Transmitting Transducer Overflow Ring Transducer for Marine Detection
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.
