HSRHC-7
HSRHC-7
High Frequency 20Hz-200kHz Cylindrical Hydrophone Receiving Transducer for Hydroacoustic Measurement
HSRHC-7 hydrophone is mainly used to receive underwater acoustic signals. It is a kind of piezoelectric transducer with a cylindrical shape. Its main features are small size, diameter φ9.5x length 44.3mm, horizontal non-directional, and vertical plane directional. It has a small size and a wide frequency range, and can be used as a standard hydrophone within 100kHz. The sensitivity response is flat, suitable for broadband noise testing. Its sensitive element is piezoelectric ceramic, which is a fragile item, so it should be handled with care during transportation and use, and it should be protected; it should also be stored in a ventilated, dry, and cool place to avoid aging of the cable rubber.

5.the external dimensions and the definition of the core wire at the end of the cable
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.
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;
