Rugged data acquisition modules

15 November 2017 Test & Measurement

New from National Instruments is the FieldDAQ range of rugged, distributed and synchronised data acquisition devices.

The growing sophistication of complex electromechanical systems, such as vehicles, aircraft and industrial equipment, means that validation test must become more rigorous to keep pace with innovation. The automotive industry in particular faces strict requirements from evolving government standards and rising customer expectations for new features such as advanced driver assistance. To help ensure the safety, reliability and quality of these systems, acquiring accurate data during testing is fundamental.

To meet these needs, test engineers are moving away from centralised measurement systems that can be susceptible to noise, and toward distributed measurement nodes, in which the digitisation and signal conditioning occurs as close to the sensors as possible. Yet more distributed measurement topologies create new challenges. Not only must DAQ devices withstand harsh test environments, they must also acquire synchronised data over an entire system and scale and integrate seamlessly.

NI’s new FieldDAQ devices are the most rugged NI DAQ devices ever created; they can acquire accurate, reliable measurements in the most severe test cell and outdoor environments, including rain, sleet, snow or mud. FieldDAQ devices have an ingress protection rating up to IP67 (dust and water resistant), can operate in -40°C to 85°C environments and can sustain 100 G shock and 10 G vibration.

FieldDAQ also incorporates Time Sensitive Networking (TSN), the next evolution of the IEEE 802.1 Ethernet standard, providing extremely tight synchronisation over a distributed network of DAQ nodes without additional cabling or complex programming.
