Dragonfly Family

The Dragonfly provides a family of rugged 8-channel small form factor Data Acquisition (DAQ) modules with built in Signal Conditioning options.

All Dragonfly units includes HGL’s standard interface connections presented on the Hardware Overview page. This means that all Dragonfly units can connect with and operate with any other HGL Modular Front-Ends.

Dragonfly is presented in 450mm x 450mm x 50mm Milled Aluminium Hard Anodised Chassis with milled T-slots to allow multiple modules to be joined together for larger channel count systems.

Dragonfly is intended for relatively hostile Environmental locations including close to Test Vehicle applications. The modules are rated to IP64/65 depending on Signal Conditioing options.

All Dragonfly units are supported fully by HGL’s Data Acquisition Software.

Features

8 Channels

Dragonfly Front Ends are provided 8 channel modules only in a 450mm x 450mm x50mm form factor.

Multiple Conditioning Types

Depending on Signal Conditioning option(s) chosen, Hummingbird can support Voltage, IEPE, Bridge (all types), Dynamic Strain, SE & DF Charge (including High Temperature sensors), 4-20mA, RTD (PRT) and TC each channel.

Multiple Synchronizing Types

Hummingbird natively supports IEEE-1588 (PTPv2) and HGL LVDS for precise synchronisation to < 50nS resolution across entire systems. IRIG A/B and GPS are optionally available.

Simultaneous Sampling

Dragonfly supports individual Sigma-Delta ADCs per channel synchronized to better than 10ns across individual units.

Flexible Sample Rates

Dragonfly allows sample rates from 1kHz to 256kHz (in 1Hz steps) to be chosen for each block of 8 channels. Due to careful design the majority of these sample rates are precise.

140dB Dynamic Range

Dragonfly utilises instrumentation grade Sigma-Delta 24-bit ADCs across the range. These provide up to 140dB Dynamic Range and with oversampling rates to 1024x provide superb anti-alias capabilities.

Flexible Power

All Dragonfly models support DC power from 9 to 36V (automotive ranges) and PoE to 802.3bt (100W) standard.
AC power supplies are supported through a range of external adaptors

Environmentally Sealed

Dragonfly has been designed to be used in relatively challenging environments and all models have no exterior openings and are sealed to IP64/65 (min) standard against water ingress.

Rugged

In addition to the environmental sealing, the Dragonfly range are intended for use in relatively harsh vibration environments in test cells close to test vehicles and even on test vehicles.

Conduction Cooled

All Dragonfly models are conduction cooled through innovative internal design and materials.
All models are able to operate accurately from -55 to +80C.

Flexible and Scalable

Every HGL DAQ module is fully interoperable with other DAQ modules and this includes Hummingbird. Connection of multiple units is simple and quick and allows complex systems up to and above 1000 channels to be realised easily

Dragonfly Models

Dragonfly is available in a range of models and signal conditioning options.

The table below indicates the Signal Conditioning types in the first column and the types of conditioning supported by that type.
