| Definition | A high-frequency omni-directional hydrophone and sound projector for use in the marine environment. It comes with a pre-amplified output of 0 to 35 dB (selectable on order) with current or voltage signalling. It has a diameter of 13 mm and length of 148 mm (single package). It is depth-rated to 3500 m and can operate at temperatures between -40 and +70 degC. Its voltage sensitivity without pre-amp is -200 +/- 1.5 dBV re 1uPa, and -165 +/- 1.5 dBV re 1 uPa with pre-amp. Its lowest resonance frequency is 170 kHz and capacitance is 1.4 nF +/- 20 % at 20 degC. |
