Key product information and technical features.
NI WSN-3226 is an NI Wireless Sensor Network node that NI identifies as a “4-Channel, 20-Bit Voltage/RTD Node.” In NI documentation, the WSN-3226 is presented as a field measurement node within a WSN system, distinct from gateway products such as the NI WSN-9791 and NI 9792 WSN Real-Time Gateway. This establishes the device family as NI Wireless Sensor Network hardware, while the specific SKU discussed here is the base WSN-3226 model designation.
The model-specific calibration procedure confirms four channels, 20-bit measurement resolution, and support for voltage plus resistance/RTD-related configurations. NI calibration data shows a 10 V voltage range verified at +9.95 V, 0 V, and -9.95 V, supporting use on a bipolar voltage range centered on ±10 V. The same NI procedure lists resistance/RTD settings of 400 Ω / Pt100, 4 kΩ / Pt1000, and 100 kΩ, making the WSN-3226 suitable for low-level voltage and RTD or resistance measurements within the NI WSN architecture.
For deployment, NI states that WSN-3226 nodes can operate from four AA alkaline batteries or from a 5–30 V power supply. The official NI software documentation states the WSN-3226 requires LabVIEW 2010 or later, and NI’s software support matrix further lists LabVIEW WSN Module 2010 or later with NI-WSN 1.3.0 or later for this device. These references are important when verifying compatibility for legacy or maintained NI Wireless Sensor Network installations.
