Type 8105 (Spherical Hydrophone)

Spherical hydrophone with rugged construction capable of withstanding pressures of up to 9.8 MPa (100 atm; 1000 m (3250 ft) ocean depth) and featuring exceptional directional characteristics. A small, spherical transducer for making absolute sound measurements over the frequency range 0.1Hz to 160 kHz with a receiving sensitivity of −205 dB re 1V/µPa. It is rugged, being capable of withstanding pressures of up to 107 Pa (100 atm.; 1000 m (3250 ft.) ocean depth). This hydrophone has excellent directional characteristics: at 100 kHz, it is omnidirectional over 360° in the x-y (radial) plane and 270° in the x-z (axial) plane.

Features

Sensitivity: 0.056 mV/Pa | Lower frequency: 0.1 Hz | Higher frequency: 160 kHz | Maximum operating static pressure: 260–265 dB (9.8×10^6 Pa) depending on variant | Mounting space: 93 x 22 x 93 mm (3.66 x 0.87 x 3.66 in)
