Hummingbird Front Ends are provided with 16 / 24 / 32 channels in the standard 2U and 3.5U chassis
The Modular Hummingbird 4U chassis allows up to 8 DAQ modules to be fitted to provide channel counts up to 64 channels in a single chassis
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 on each channel.
Hummingbird natively supports IRIG A/B, IEEE-1588 (PTPv2) and HGL LVDS for precise synchronisation to < 50nS resolution across entire systems. GPS is optionally available.
Hummingbird supports individual Sigma-Delta ADCs per channel synchronized to better than 10ns across all channels in the unit.
Hummingbird 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.
Hummingbird 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.
All Hummingbird 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
Hummingbird has been designed to be used in environmentally challenging environments and all models have no exterior openings and are sealed to IP65 (min) standard against fluids including jet fuels, lubricants etc.
In addition to the environmental sealing, the Hummingbird range are intended for use in harsh vibration environments in test cells close to test vehicles and even on test vehicles.
All Hummingbird models are conduction cooled through innovative internal design and materials.
All models are able to operate accurately from -55 to +80C.
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
Hummingbird is available in a range of models and signal conditioning options. The most popular units provide the same conditioning for all channels, but HGL Dynamics can provide mixed conditioning models on request.
The table below indicates the Signal Conditioning types in the first column and the types of conditioning supported by that type.
