High-precision ultrasound measurement according to established standards
The Hydrophon - HGL series was developed to reliably meet the requirements of demanding ultrasonic measurements. The series complies with the recommendations of the AIUM Acoustic Output Measurement Standards and is particularly suitable for determining acoustic intensity and for general field mapping. Thanks to its exceptionally flat sensitivity characteristics, the hydrophone delivers reproducible and near-standard measurement results, even in compact measurement setups. This makes the HGL series a proven solution for research facilities, development departments and quality assurance. .
High sensitivity in a compact design
A key feature of the Hydrophon - HGL series is the combination of high sensitivity and very small effective aperture. This design enables a precise spatial resolution of the sound field, even at high frequencies. At the same time, the broadband design supports a frequency range from around 250 kHz to over 20 MHz with a flatness of ±3 dB. In conjunction with suitable preamplifiers, measurements can even be realized up to the range of 40 MHz and beyond. .
Different aperture sizes for flexible applications
The HGL series is available in several versions with different electrode apertures, including 85 µm, 200 µm and 400 µm. This allows the hydrophone to be specifically adapted to the respective measuring task. While smaller apertures offer a very high directional characteristic and a large acceptance angle, larger apertures are particularly suitable for robust standard measurements. This flexibility makes the hydrophone - HGL series a versatile tool for a wide range of ultrasonic applications. .
Robust construction and reliable calibration
In addition, the Hydrophon - HGL series is characterized by its solid and durable construction. The robust design supports reliable use in everyday laboratory work as well as in automated measuring systems. All models are supplied with a traceable calibration in the range from 1 to 20 MHz, ensuring a high level of comparability and measurement reliability. In combination with compatible preamplifiers, the hydrophone can be seamlessly integrated into existing measurement chains and used as an internal reference system.
