Using remote data acquisition units in harsh environmental conditions

There are a number of reasons why a smaller size chassis is advantageous in aerospace applications. Obviously, size is at a premium on aircraft and any steps that can be taken to free up more room is welcome. For many programs, a more important issue is the added weight and complexity of wiring. Extra weight on aircraft translates to higher fuel burn which means extra cost. Apart from reduced weight there are other advantages to a reduction in wiring such as easing installation and helping to get more accurate data
The trend to move the data acquisition chassis closer to the sensor leads to many challenges for the design of a data acquisition chassis. Using a COTS modular approach has the advantage that the same acquisition cards can be used in all chassis regardless of whether they are located in the cabin or remotely. However, in some cases the small space envelopes available for the installation of the chassis lead to the requirement for a specialized miniature chassis.
The Using remote data acquisition units in harsh environmental conditions white paper discusses the challenges of designing a small data acquisition system which can provide hundreds of channels of measurement capability while operating in tight spaces which are exposed to high vibration and extremes of temperature.
