TThe SQ48-00 hydrophone is made with a piezoelectric ceramic sphere. The piezo
element offers transmit capability at a 145 kHz resonance and a broadband receive
capability. Mounting options and connector types can be modified to meet customer
requirements. The piezo sphere can also be wired in series, to increase receive
sensitivity. The SQ48-00 can be paired with a preamplifier with a standard 40 dB
gain, for an effective sensitivity of -170 dB. Custom preamps are available. Contact
us to discuss your specific requirements.
