HGL supplies five Dragonfly based systems for submersible self-noise applications.

Dragonfly, with its totally silent, conduction-cooled architecture and world-class data acquisition capabilities, is ideal for measuring noise and vibration in sensitive environments. This summer, HGL has supplied five systems to a European Navy for use aboard submarines measuring self-noise generation. Each system is based on a single Dragonfly acquisition module, a CPU module, a Display module for control and monitoring, and a number of solid state storage modules to transfer data onshore for further analysis.

The systems provide monitoring information to the user in the form of FFTs, spectrograms, waterfalls, oscilloscopes etc, and provide automatic conversion of HGL data to standard WAV format for import into the shore-based analysis equipment.

The solution is completely silent and occupies a volume of less than 6" x 6" x 12" (15 cm x 15 cm x 30 cm).

HGL's Dragonfly system has been developed as a small footprint, rugged data acquisition system for use in aerospace, industrial and automotive applications. It provides acquisition bandwidths of up to 100 kHz at 24-bit resolution. More details on the Dragonfly range of modules can be found by clicking this link.
