National Instruments WSN-3214 wirelss strain/bridge completion node and NI 9232 data acquisition card

National Instruments has announced two products to help engineers monitor machines, heavy equipment and ageing infrastructure. Engineers can integrate the wireless sensor network (WSN) strain node and C Series module with NI CompactRIO for predictive maintenance to predict faults, analyse fatigue, lower operating costs and decrease downtime.

The WSN-3214 strain/bridge completion node features hardware-timed waveform acquisition and is suitable for wireless structural health monitoring of bridges, buildings and equipment. It has four analog input channels that support quarter-, half- and full-bridge completion, and also two digital I/O channels for event detection and programmatic control. It has the ability to perform onboard data processing, save data locally or predict fault conditions with the NI LabVIEW WSN Module.

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. It has a ±30 V input range, 4 mA IEPE current excitation and 41 kHz bandwidth. Screw terminals and open/short sensor detection are provided for use in permanent industrial monitoring applications.
