20Hz-100kHz Cylindrical Hydrophone Receiving Transducer for Hydroacoustic Measurement

20Hz-100kHz Cylindrical Hydrophone Receiving Transducer for Hydroacoustic Measurement

The HSRHC-14 hydrophone and the HSRHS-20 hydrophone are similar in frequency range and sensitivity, but the HSRHC-14 hydrophone is cylindrical and the HSRHS-20 hydrophone is spherical. It has the following characteristics: (1) Good directivity. It is non-directional in the horizontal plane and directional in the vertical plane. (2) It has a wide frequency range and can be used as a standard hydrophone within 100kHz. (3) It has a flat sensitivity response and is suitable for testing broadband noise. (4) According to user needs, it can be built-in with a preamplifier for signal amplification and long-distance transmission.
