Reliable signal processing for precise hydrophone measurements<\/h1>\n

Hydrophon preamplifier and accessories<\/strong> are a central component of modern ultrasonic measuring systems. The AH-20\u00d70 preamplifier series from ONDA was specially developed as an electronic and mechanical supplement to ONDA hydrophones. Thanks to their very flat frequency response, low inherent noise and high stability, these preamplifiers support precise and reproducible acquisition of acoustic signals. This makes them particularly suitable for demanding applications in acoustic intensity measurement and hydroacoustic research.<\/p>\n

Submersible design for easy integration<\/h2>\n

A key feature of the Hydrophon preamplifier and accessories<\/strong> is the fully submersible version of the AH series. The preamplifier is connected directly to the hydrophone and only requires a single coaxial cable to the measuring device outside the water tank. This design significantly reduces the amount of cabling required in the measurement setup and minimizes potential interference. The watertight connection design ensures a secure connection to ONDA hydrophones and at the same time supports compatibility with other hydrophone types.<\/p>\n

High bandwidth and low noise<\/h2>\n

The AH-20\u00d70 preamplifiers cover a wide frequency range from around 50 kHz to 100 MHz and can therefore be used in a wide variety of ultrasonic applications. The low noise level and wide dynamic range mean that even weak signals can be reliably amplified. These properties are particularly relevant for the detailed analysis of ultrasonic fields, where high signal quality is crucial.<\/p>\n

Flexible amplification and convenient operation<\/h2>\n

Within the Hydrophon preamplifier and accessories<\/strong> the AH-2020 offers additional flexibility with a switchable gain of 0 dB or 20 dB. Switching can be done either via a switch or via TTL signal directly from the oscilloscope. This allows the preamplifier to be optimally adapted to different measurement conditions without changing the setup. The AH-2010, on the other hand, offers a fixed gain and is suitable for standardized measurement tasks with constant requirements.<\/p>\n

Complete accessories for immediate use<\/h2>\n

The scope of delivery of the Hydrophon preamplifier and accessories<\/strong> includes a comprehensive set of components, including power supply, DC block, coaxial cable, adapter and a calibration certificate. The hermetically sealed stainless steel housing ensures a long service life even with intensive use. Thanks to the traceable calibration supplied, measurement results can be reliably documented and compared. All in all, the AH-20\u00d70 preamplifiers offer a professional and sophisticated solution for precise ultrasonic measurements in the laboratory and in development.<\/p>","protected":false},"excerpt":{"rendered":"
