1 Description
The flightDAQ is a self-contained acquisition system and combined pressure scanner that acquires
and transmits data to a host via Ethernet or a CAN bus all contained within a heated box. It is a variant
of the popular Chell MicroDaq pressure acquisition system that has been subjected to enhanced
testing in line with the expectations of flight test environmental conditions. Full details of the tests are
available on request.
The flightDAQ comes in several variants to accommodate both conventional HD series scanners and
Digital Thermal Compensation (DTC) scanners with 32 and 64 channels. The flightDaq2 features an
SQDC quick disconnect coupling for the measurement lines meaning a wide variety of tubing types
can be connected to it. Other pneumatic interfaces are also available.
The flightDAQ contains all the necessary valving to control the internal scanner valve for re-zero and
purge operations.
The flightDAQ has within it an embedded web server for configuration and data review. It can also be
used with the MicroDaqX software to display and log the data to disk. For data synchronisation, the
flightDaq2 features IEEE 1588 PTPv2 time stamping and a hardware trigger.
All electrical connections are made to the flightaq2 through one connector. To make connecting up
easier, Chell can supply a cable and interface with standard connectors on it (RJ45 for Ethernet, D
type for CAN and BNC for hardware trigger).
