Transducer Cylinderical Hydrophone for Underwater Acoustics

    Transducer Cylinderical Hydrophone for Underwater Acoustics

1. The standard hydrophone has the following characteristics:

 

1. Good directionality. The hydrophone has no directivity horizontally, and no directivity within 240° of the vertical plane.

2. The frequency range is wide, which can cover most of the frequency bands for underwater acoustic measurement.

3. Flat sensitivity response.

4. Good stability and high reliability.

 

2. The main technical indicators of standard hydrophones:

 

Operating frequency range: 20Hz～100kHz

Linear frequency range: 20Hz～50kHz

Low frequency receiving sensitivity: -198dB

Horizontal directivity: ±1.5dB (100kHz)

Vertical directivity: ±2.0dB (100kHz, 240° range)

Maximum working depth: 500 meters

Definition of the core wire at the end of the cable: red wire-signal +; black wire-signal -; shielded wire-ground wire; the standard length of the cable is 15 meters

 

6. Precautions for use and storage:

1. The standard hydrophone is a fragile item, handle it with care during transportation and use, and pay attention to protection;

2. The standard hydrophone should be stored in a ventilated, dry and cool place to avoid rubber aging;
