The SQ42-00 hydrophone is made with a piezoelectric ceramic sphere. The piezo element offers transmit capability at a 320 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 SQ42-00 can be paired with a preamplifier with a standard 40 dB gain, for an effective sensitivity of -175 dB. Custom preamps are available. Contact us to discuss your specific requirements.
