10khz-800khz Broadband Miniature Reference Hydrophone with Internal Preamplifiers
We independently developed acoustic transducer products cover a full range of hydrophones, transmitting transducers, transceiver transducers, sonar array transducers and ultrasonic transducers, covering overflow rings, flextensional and curved discs. and composite materials, etc., achieving full coverage from low to medium frequency to high frequency, from shallow water to 10,000-meter water depth, and can be widely used for listening and homing detection, communication networking, positioning and navigation, seabed surveying and mapping, forward-looking side scanning, industrial and medical ultrasound and other types of acoustic equipment.
Specification:
The PH4035 is a miniature probe hydrophone specifically designed as a standard reference hydrophone for sound measurements in the frequency range 100 to 500kHz. The hydrophone incorporates a 10dB low-noise preamplifier, which includes an insert calibration circuit for convenient electrical testing of the hydrophone condition. The pre-amp has a drive capability for cable length up to 25 meters.The hydrophone offers a useable frequency range from 10 to 800kHz with good omnidirectional characteristics in the horizontal and the vertical plane.
Key Features:
Reference hydrophone for high frequencies
Linear receiving response from 100kHz to 500kHz
