National Instruments WSN-3214 strain node and NI 9232 C Series Module for embedded monitoring

National Instruments has released two new 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.

With NI wireless sensor networks and the WSN strain node, critical structures can be monitored without excessive cables. Programmable WSN nodes are used with LabVIEW for onboard analysis of strain data to achieve an in-depth understanding of structural response.

Features for the WSN-3214 strain node include: four analog input channels that support quarter-, half- and full-bridge completion, two digital I/O channels for event detection and programmatic control, and the ability to perform onboard data processing, save data locally or predict fault conditions with the NI LabVIEW WSN Module.

The NI 9232 C Series Module includes a ±30 V input range, 4 mA IEPE current excitation and 41 kHz bandwidth, as well as screw terminals and open/short sensor detection for use in permanent industrial monitoring applications.

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.
