NI embedded monitoring products for preventative maintenance

The NI WSN-3214 strain/bridge completion node features hardware-timed waveform acquisition and is suitable for wireless structural health monitoring of bridges, buildings and equipment.

With expanded voltage range, faster sampling rates and higher integrated electronic piezoelectric (IEPE) excitation, the NI 9232 C Series module is a data acquisition card optimised for industrial accelerometers, tachometers and proximity probes in condition monitoring applications.

Sharon L. Wood, Professor and Department Chair of Civil, Architectural and Environmental Engineering at The University of Texas at Austin, says: "With NI wireless sensor networks and the new WSN strain node, we can easily monitor critical structures without excessive cables. We use WSN nodes that are programmable with LabVIEW for onboard analysis of strain data to achieve an in-depth understanding of structural response."

WSN-3214 Strain Node

• Four analogue input channels that support quarter-, half- and full-bridge completion
• Two digital I/O channels for event detection and programmatic control
• Ability to perform onboard data processing, save data locally, or predict fault conditions with the NI LabVIEW WSN Module

NI 9232 C Series Module

• +/-30V input range, 4mA IEPE current excitation and 41kHz bandwidth
• Screw terminals and open/short sensor detection for use in permanent industrial monitoring applications
