LHP Hydrophone System
- Overview
- Features
- Specifications
- Applications
The LHP_1
(formerly the HPA_0_2) is designed for operation within a bandwidth
of 20-80 kHz . It can be used for both datalogging and manual
tracking applications. It incorporates an amplifier that generates
a differential signal drive, enabling cable runs of up to 1000
meters.
Some of the key features
of the LHP Hydrophone System:
- Works in association with a receiver to detect transmitter
signals
- Capacity for manual tracking and datalogging
- Can be configured for either omni-directional or directional operation
| Model | Depth Rating | Acoustic Frequencies |
Sensitivity
dB re 1V/ µPa |
| LHP_1 | 40 m | 65.5 / 76.8 kHz |
-171 |
| LHP_2 | 40 m | 200 kHz | -171 |
| LHP-3DF | 900 m | 200 kHz | -186 |
Examples
of applications for which the LHP hydrophones are ideally suited include:
- tracking of marine fish and wildlife
- tracking of juvenile marine fish in high noise environments such as at a dam face or an ocean reef
- aquatic applications characterized by water with high conductivity, or deep water
- manual tracking or datalogging applications where the hydrophone is not required to be a considerable distance away from the receiver
