The National Instruments WSN-3214 Strain/Bridge Node is an integral component designed for use within National Instruments Wireless Sensor Networks (WSN). This versatile device features four analog input channels that can be configured for half-, full-, or quarter-bridge completion on a per-channel basis, making it suitable for a variety of strain gauge applications. Equipped with a flexible analog front end, the WSN-3214 allows users to define waveform size, sample rate, and waveform interval, thus meeting diverse application needs with high-resolution and high-speed analog input modes.

The node is specifically engineered for wireless connectivity and can be powered by batteries, requiring replacement or recharge approximately once every three years under optimal conditions. It also supports redundant power supplies for greater reliability. The WSN-3214 can be mounted on a 35 mm DIN rail or a panel, and mounting accessories are available for separate purchase from National Instruments. In a typical deployment, the WSN-3214 integrates seamlessly with a WSN gateway, which can manage up to 36 wireless nodes, allowing for efficient wireless signal analysis and monitoring. Users can utilize a host PC running Microsoft Windows or a CompactRIO Chassis to connect to the wireless network system, providing access to real-time measurements and configuration details.

Although designated as a mature product, the WSN-3214 remains accessible for purchase and repair, providing ongoing support and reliability in industrial applications.
