Low-Noise Hydrophone with Preamplifier
Hydrophone Type 8106 features a built-in, thick-film, and low noise, 10 dB preamplifier, delivering signal conditioning for transmission over very long distances. This makes Hydrophone Type 8106 suitable for underwater sound measurements down to 1000 meters depth.Request Price
Type 8106 is a wide-range, piezoelectric hydrophone with preamplifier for making absolute sound measurements over the frequency range 7Hz to 80 kHz, featuring an impressive receiving sensitivity of −173dB re 1V/μPa.
- Calibration reference standards
- Ultrasonic measurements in liquids
- Cavitation measurements
- Laboratory and industrial measurements in liquids and gases
- As underwater projectors (8103, 8104 and 8105)
- Noise measurements in humid and polluted atmospheres
An integrated watertight connector allows quick disconnection of the cable and makes replacement and storage very easy.
The hydrophone is built to withstanding high static pressure, the operational upper limit being 107 Pa (100 atm / 1000 m (3250 ft.) ocean depth.
