Renke High Accuracy Three Axis Wind Speed Wind Direction Sensor 3D Ultrasonic Anemometer

Three pairs of opposing ultrasonic transducers capture X-axis, Y-axis, Z-axis wind speed, horizontal wind direction, vertical wind direction, and total resultant wind speed in one device.

No minimum wind speed required to begin measurement, enabling accurate data capture at near-zero wind conditions where mechanical anemometers with inertial startup thresholds fail entirely.

Advanced acoustic phase compensation eliminates inertial delay, capturing high-frequency gust fluctuations in wind that mechanical cup-and-vane systems cannot resolve due to rotational inertia.

Beyond wind data, the sensor outputs sound propagation speed at plus or minus 0.5% accuracy and derives acoustic temperature at plus or minus 0.5 degrees C.

Six transducers are mounted on high-quality stainless steel support columns that resist mechanical deformation and chemical corrosion, maintaining probe alignment under sustained 75 m/s wind loads.

Housing geometry actively discourages particulate settlement and ice buildup on transducer surfaces, reducing measurement interference during winter storms and dusty.

Each transmitting and receiving transducer undergoes independent wind tunnel testing and calibration before assembly, ensuring per-unit measurement accuracy rather than batch-level calibration.

Vector averaging accounts for wind direction when averaging speed, suited for pollutant dispersion tracking. Scalar averaging matches traditional mechanical anemometer output for energy generation.

Waterproofed to IP66 and structurally rated to survive 75 m/s wind gusts, enabling year-round deployment at exposed coastal, mountain, wind farm, and airport monitoring sites.
