NI Wi-Fi DAQ devices

National Instruments has introduced 10 new Wi-Fi and Ethernet data acquisition (DAQ) devices, extending the NI measurement hardware and software platform to wireless remote monitoring applications. The new wireless and Ethernet DAQ devices include built-in signal conditioning and direct sensor connectivity for electrical, physical, mechanical and acoustic signals.

NI says that engineers and scientists can combine NI Wi-Fi DAQ with the NI LabVIEW software platform to meet their wireless structural diagnostic, environmental and machine condition monitoring application needs by reducing cabling costs and increasing flexibility without compromising performance.

Using the IEEE 802.11 standard for wireless networks, the new NI Wi-Fi DAQ devices stream data on each channel at more than 50 kS/s with 24 bits of resolution. Wi-Fi DAQ devices deliver measurement data to a host PC instantaneously for real-time viewing and in-line analysis of dynamic sensor signals. NI claims that the built-in network authentication methods and 128-bit AES encryption offer the highest commercially available network security and meet the standards defined for use of wireless networks in U.S. government facilities by the National Institute of Standards and Technology.

Wireless technology extends NI data acquisition hardware and software technology to new distributed and portable measurement applications where wiring is difficult or cost-prohibitive. NI says that the flexibility of LabVIEW graphical programming and the ubiquity of Wi-Fi network infrastructure make it easy to incorporate wireless sensor measurements into new or existing PC-based measurement or control systems.

The Wi-Fi and Ethernet DAQ devices are shipped with NI-DAQmx driver software and NI LabVIEW SignalExpress LE. WiFi and Ethernet devices start at Rs.29,958.06 ($699) and Rs.25,672.22 ($599) respectively.
