DAQ System Gets Down And Dirty

National Instruments’ (NI) distributed and synchronized FieldDAQ data-acquisition (DAQ) devices are touted as the most rugged NI DAQ devices ever created; they can acquire accurate, reliable measurements in the most severe test cell and outdoor environments. Sophistication of complex electromechanical systems requires validation/test systems to be more rigorous. One example is the automotive industry’s strict requirements from evolving government standards and expectations for advanced driver assistance systems (ADAS).

 

To meet these needs, test engineers are moving away from centralized measurement systems that can be susceptible to noise, and toward distributed measurement nodes, in which the digitization 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 synchronized data over an entire system and scale and integrate seamlessly.

SENSORS EXPO & CONFERENCE

Sensors 2018 Hits Silicon Valley June 26-28!

Join thousands of engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, including AI, Autonomous Vehicles, IoT, and Medical, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.

 

NI claims its FieldDAQ devices 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 100g shock and 10g vibration.

 

FieldDAQ also incorporates Time Sensitive Networking (TSN), the next evolution of the IEEE 802.1 Ethernet standard, providing extremely tight synchronization over a distributed network of DAQ nodes without additional cabling or complex programming. FieldDAQ expands the NI TSN product offering, joining Industrial Controllers, CompactDAQ and CompactRIO. Additionally, because it incorporates TSN, FieldDAQ is capable of being used with third-party TSN solutions from major industrial I/O and control vendors like Bosch Rexroth, B&R Automation and Schneider Electric.
