HGL Dynamics presents its Dragonfly range of miniature high-performance data acquisition cards and support modules.

The world of digital data acquisition has matured over the past few years, with a range of vendors (including HGL Dynamics) offering high-quality and performance data acquisition products in a variety of form factors, with one exception: miniature, vehicle-mounted, high-performance and ultra low-power modules. Dragonfly from HGL fills this area.

Dragonfly provides not only Data Acquisition modules, but also support modules such as:

  • Core2 Duo, Core i5, and Core i7 CPU modules powerful enough for any measurement task,
  • Solid State Disk (SSD) modules for extended removable storage needs,
  • Battery / UPS power modules for 6 - 30 V DC inputs
  • Gigabit Ethernet Switches with Power Over Ethernet (POE) capability
  • Ethernet connected remote control / display unit
  • More information on specific modules is available on our Dragonfly section.

All modules are rated to IP64 and are produced in extruded aluminium chassis for robust all-weather operation.

For further information either visit our Dragonfly pages or call your local HGL Dynamics office or representative for delivery and pricing information.
