Overview
TR-PH20 is a two-dimensional differential pressure vector hydrophone optimized for 20kHz band. It simultaneously captures acoustic pressure and particle velocity information in the XY plane to realize passive azimuth estimation of underwater sound sources.
The working frequency covers 20–30kHz, suitable for medium-frequency underwater acoustic detection and positioning. It delivers excellent lateral rejection and low directional asymmetry, ensuring stable direction-finding performance.
Size Φ50×H70mm (incl. cable), weight in air 350g. It adopts threaded housing for easy installation, and mechanical structure can be customized to match vector arrays, underwater monitoring platforms and experimental tank systems.
Applications
- Underwater vector direction-finding array
- Medium-frequency underwater acoustic localization
- Shallow water target detection
- Water tank acoustic calibration and vector acoustic experiments
- Underwater acoustic communication auxiliary bearing measurement
- Small AUV and underwater monitoring equipment acoustic sensing
