Short Description:

The LoPAS series consists of ultra-low-power, self-contained underwater acoustic sensing devices. Featuring embedded low-noise signal processing modules and utilizing piezoelectric sensing technology, these devices enable the simultaneous acquisition of underwater acoustic signals and depth/temperature data, as well as long-duration, autonomous recording. The devices’ self-noise levels are lower than those of Sea State 0 conditions; furthermore, their ultra-low-power architecture ensures stable and reliable operational endurance. The series supports synchronized multi-device array deployment—achieving synchronization accuracy superior to 1 μs—with array apertures capable of covering the full ocean depth.

The LoPAS series employs a universal mounting structure, allowing for easy integration into various platforms such as subsurface moorings, buoys, and offshore observation stations. It is widely applied in fields including marine acoustic surveys, offshore scientific research, bio-tracking, wind farm noise monitoring, and underwater environmental impact assessments.
