Microphones and hydrophones ZETLAB MPA 216 , etc.
Hydrophones operate on the basis of the piezoelectric effect principle, which allows them to be used both as linear and reversible hydroacoustic transducers.
Hydrophones meet the requirements of undistorted sound field, wide frequency range and lack of directionality of action.
Models: SUN 311, SUN 312, SUN 313, SUN 314-M, ZET 323, ZET 321, ZET 351, ZET 330.
Microphones are primary converters that allow converting sound pressure into an electrical signal.
Models: 4160N, SI-522, ZET501, MPA265, MPA261, MPA216, MPA215, MPA201.
The SI522 sensor consists of a reliable frame on which two ICP preamps and matched microphones are mounted, pointing at each other. The distance between the microphones is set using struts made of hard plastic. The sound affects each microphone through a narrow gap between the spacers and the microphone grid. This allows for strict acoustic separation of microphones and minimizes the influence of acoustic shadows and reflections.
The SW series impedance tubes are used to accurately measure the absorption coefficient and impedance in accordance with ISO 10534-2 (1998).
The sound intensity measurement kit senses the sound pressure and converts the received values into electrical signals. The spectrum analyzer ZET 017-U performs signal processing from the kit, averaging and calculations necessary to determine the sound intensity.
A matched microphone pair of the MPA215 type is used in the kit, which allows measuring sound intensity in the frequency range from 20 Hz to 12.5 kHz.
