日本av电影网站The Brüel & Kjær range of Hydrophones which are used for a variety of underwater research and automotive applications.All this range of hydrophones is a range of individually calibrated, waterborne-sound transducers that have a flat frequency response and are omnidirectional over a wide frequency range. Their construction is such that they are absolutely waterproof and have good corrosion resistance.
Noise measurements in humid and polluted atmospheres
Calibration reference standards
Laboratory and industrial measurements in liquids and gases
As underwater projectors (8103, 8104 and 8105)
Ultrasonic measurements in liquids
Four types of Hydrophone:
- Type 8103 is suitable for laboratory and industrial use and particularly for the acoustic study of marine animals or for cavitation measurements.
- Type 8104 is ideal for calibration purposes.
- Type 8105 is a robust spherical hydrophone usable down to 1000 m ocean depth with excellent directional characteristics,being omnidirectional over 270° in the axial plane and 360° in the radial plane.
- Type 8106 has a built-in amplifier which gives a signal suitable for transmission over long underwater cables.It is usable down to 1000 m ocean
