The NI WSN-3214 is the ideal product for your wireless structural health monitoring applications. Eliminate the need for costly and prohibitive wiring by implementing a wireless monitoring solution from a worldwide leader in measurements.

The WSN-3214 measurement node adds support for hardware-timed waveform acquisition to the NI wireless sensor network (WSN) platform. It features four analog input channels that you can configure on a per-channel basis for quarter-/half-/full-bridge completion or strain gage measurements. With the flexible analog front end, you can define sample rate, waveform size, and waveform interval and use the high-speed and high-resolution analog input modes to configure the node to meet your unique application needs.

With the LabVIEW WSN Module, you can use graphical programming to customize the node’s behavior and add intelligence to perform local control, analysis, and data reduction. For example, you can program the device to acquire a strain waveform, perform peak detection or rainflow analysis locally on the node, and then transmit only meaningful or important data back to the gateway, which reduces radio traffic and prolongs the battery-powered lifetime of the device.

The WSN-3214 also features two bidirectional digital channels with industrial voltage ranges that you can configure on a per-channel basis for input, sinking output, or sourcing output. The 36-position Weidmuller connector delivers direct connectivity to transducers. You can power the measurement node with four 1.5 V, AA alkaline or lithium battery cells, or you can externally power the node with a 5 to 30 V supply (not included). This node features support for battery backup, so if it loses external power, the node automatically switches to battery power without losing data or disconnecting from the network.

A 2.4 GHz radio is used to wirelessly transmit data to the WSN gateway, where you can connect to other devices in your system. NI-WSN software delivers easy network configuration in NI Measurement & Automation Explorer (MAX) and data extraction with NI LabVIEW software.

You can configure the WSN-3214 as a mesh router to increase network distance and connect more nodes in your WSN system. You can connect eight end nodes (star topology) or up to 36 measurement nodes (mesh topology) to a single WSN gateway, with outdoor ranges up to 300 m with line of sight. The device also offers industrial temperature and shock and vibration ratings.
