Product details
Product introduction
SinoTD7 is a low-frequency transducer with both transmit and receive functions. Relying on its excellent acoustic performance, it can be adapted to a variety of underwater acoustic application scenarios. This transducer features broadband operation and outstanding transmit/receive capabilities, meeting the requirements for efficient transmission and sensing of underwater signals.
Its omnidirectional horizontal directivity, combined with a reasonableVertical directivity angle, enables wide-range underwater signal coverage. The compact and robust structural design allows it to withstand great underwater operating depths and adapt to complex underwater working environments, while its lightweight nature facilitates installation and deployment.
The temperature range and operating depth of this transducer meet the environmental requirements of most underwater operations. It is widely used in fields such as underwater communication, positioning and navigation, marine environmental monitoring, underwater security detection, and underwater acoustic scientific research, making it one of the core devices in the construction of underwater acoustic systems.
Main application scenarios
(1) Underwater wireless communication
(2) Underwater positioning and navigation
(3) Marine environmental monitoring
(4) Underwater security and monitoring
(5) Underwater acoustic scientific researc
