Custom Piezoelectric Cylinderical Hydrophone for Marine Detection

  Custom Piezoelectric Cylinderical Hydrophone for Marine Detection

1. Product description

(1) Good directionality. The horizontal hydrophone has no directivity, and the vertical plane has directivity.

(2) Small size, wide frequency range, can be used as a standard hydrophone within 100kHz.

(3) The sensitivity response is flat, suitable for broadband noise testing.

 

2. Working characteristics

(1) Operating frequency range: 20Hz～200kHz

(2) Linear frequency range: 1kHz～100kHz

(3) Low frequency receiving sensitivity: -217dB

(4) Horizontal directivity: ±1.5dB (50kHz)

(5) Maximum working depth: 300 meters
