Overview
TR-PH35 is a two-dimensional differential pressure vector hydrophone tuned for 35kHz. It can simultaneously acquire acoustic pressure and particle velocity information in XY plane, supporting direction-of-arrival estimation for underwater acoustic signals.
The operating band covers 30–40kHz, suitable for medium-high frequency underwater acoustic detection. It has excellent lateral rejection ratio and low directional asymmetry, delivering stable azimuth measurement performance.
Compact package φ34×H38mm (including cable), weight in air 100g. Standard threaded housing structure, and mechanical form can be customized to fit vector array, flow measurement and small underwater detection platforms.
Applications
- Underwater vector direction-finding array
- Medium-high frequency underwater acoustic localization
- Nearshore shallow water target detection
- Water tank acoustic calibration & vector acoustic experiment
- Underwater acoustic communication auxiliary positioning
- Small autonomous underwater vehicle (AUV) acoustic sensing
