Description
The Wind Sensor Set includes the research-grade plug-and-play Wind Speed Smart Sensor and Wind Direction Smart Sensor. This combination provides average wind speed, highest three-second wind gust and average wind direction for the measurement interval. These durable sensors will provide many years of accurate and reliable performance.
NOTE: Mount these on the M-CAA Full Cross Arm for proper sensor spacing for accurate wind measurement in all wind directions.
The cross arm must be mounted on a stable mast using guy wires as needed to prevent the sensors from vibrating in high winds.

| Measurement Definition | Cup revolutions are accumulated every three seconds for the duration of the logging interval. Wind speed is the average speed for the entire logging interval. Gust speed is the highest three-second wind recorded during the logging interval. | Unit vector components of wind direction are accumulated every three seconds for duration of logging interval. Average direction is calculated from the average of these. |
