Data acquisition/measurement system integrates controller and signal conditioning

August 07, 2014 // By Graham Prophet
National Instruments’ rugged CompactDAQ 4-slot controller integrates an Intel Atom processor and high-accuracy measurements into a small, affordable form factor.

By integrating the processor, signal conditioning and I/O into a single CompactDAQ system, engineers and scientists can reduce overall system cost and complexity while increasing measurement accuracy. Integrated measurement systems reduce the number of components, connections and wiring needed, where noise and additional costs are often introduced, to ensure high-accuracy measurements and cost-optimised systems.

The CompactDAQ controller features an Intel Atom dual-core processor that can run either industry-standard Windows Embedded 7 or NI Linux Real-Time for ultimate system reliability. By pairing industry-standard OS options with LabVIEW system design software, users can port LabVIEW code from existing measurement systems to these CompactDAQ controllers. Engineers and scientists can combine LabVIEW and over 60 sensor-specific I/O modules for CompactDAQ to customise data acquisition systems to meet their specific application needs.

NI designed the systems to be smaller, less expensive and more rugged, and to allow the combination of powerful processing paired with high-accuracy measurements, anywhere.

The system has; removable SD storage, hot-swappable; an integrated CAN/LIN port; four C Series Module Slots in that host a variety of I/O types, including AI, AO and DIO; and rugged form factor that allows measurements in high shock and vibration environments as well as temperatures ranging from -40 °C to 70 °C.
