About Us Learn more about our continued desire to develop top-end peizoelectric materials and products Learn More Select a category to get started . BTech provides high performance underwater acoustic transducers to the US Navy and various ocean technology-driven organizations. Customized Solutions. Order) Contact Supplier A number of engineers and scientists are working on new techniques for the manufacture of cheap but reliable underwater transducers, with one serious problem being the need to match the acoustic impedance of the transducer with that of water, but they are not there yet. Alternatively, semi-mobile underwater networks can be suspended from buoys that are deployed by a ship and used temporarily, but then left in place for hours or days [ 12 ]. Please slide to verify help help The subject of this book is the theory, development and design of electroacoustic transducers for underwater applications. The sensors are structured with a volumetrically sensitive tourmaline crystal, suspended and sealed in an insulating, oil-filled vinyl tube. These hydrophone transducers have an omni-directional beam pattern (standard) to maximize deployment and communications flexibility. My intention is to obtain a Boat depth sensor, couple it up to an arduino or shield that will provide the drive signal and measure the return signal. Pressure transducers are engineered to handle certain levels of underwater depth. At present, high-speed underwater acoustic communication requires underwater transducers with the characteristics of low frequency and broadband. Underwater Use of Ultrasonic Sensors. 2. Operating frequency：6-9 kHz . Customized Solutions. Transducers and Arrays for Underwater Sound.
