* Intrinsic noise at the input within the frequency range of 10 Hz from the frequency range upper limit.
**The limiting hydrostatic pressure is indicated for the receiving element of the hydrophone and can be limited by the technical characteristics of the cable, in the case of immersion studies.
Hydrophones BC 312 are dynamic pressure transducers with even response curve throughout the whole range of frequencies observed in any homogeneous medium, including air, sea and fresh water.
Hydrophones BC 312 are used to determine explosion pressure in the range up to 1,000 kPa, pulse duration 2-5 ms (time sensitivity: some 0.1 ms).
Hydrophones BC 312 are used in hydroacoustics for reading-through underwater signals and noise, for measuring purposes, and also as components of beamed receiver hydroacoustic antennas.
Hydrophones BC 312 can be supplied without an integrated amplifier, in such case, it can be used as a sonar transmitter.
