ABSTRACT:
A shock-hardened hydrophone comprising a sensor electrically connected to a ow output-impedance preamplifier by a circuitboard. The sensor includes two metal cups, each cup with a piezoelectric ceramic disk positioned therein for generating a potential difference between the first and second surfaces of the disk. The cups are bolted together with the circuitboard positioned between the disks. The second surfaces of the disk are in pressure contact with the cups while the first surfaces are in pressure contact with a first electrode disposed on both sides of the circuitboard. A wire connects one of the metal cups to a second electrode disposed on either side of the circuitboard thereby completing the electrical connection of the disks to the electrodes on the circuitboard. The preamplifier is mounted on the circuitboard where the input to the preamplifier is the voltage difference between the first and second electrodes.
