S-WCA-M003
Wind Speed and Direction Smart Sensor
Discontinued
Overview
Provides average wind speed, highest 3-second wind gust, and average wind direction in the measurement interval. Designed with a large wind vane area for high sensitivity, this sensor offers high accuracy at an affordable price. Has fiberglass reinforced thermoplastic cups and shielded stainless-steel ball bearings for fast response. The wind vane has metal bushings.
NOTE: the M-CAB Half Cross Arm is required for mounting.
Warning: The S-WCA wind speed and direction sensor is designed for sensitivity, not ruggedness. It is not suitable for use in the following locations:
- On tall buildings
- In the wake of wind turbines or other locations with turbulence
- In locations with icing combined with high winds
The wind sensor must be mounted on a mast secured with guy wires to prevent the sensor from vibrating in high winds. For harsh applications we recommend using one of the following RM Young wind sensors with one of our adapters: Wind Sentry Adapter, Wind Monitor Adapter, Wind Monitor AQ Adapter, or Marine Wind Monitor Adapter.

| 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. |
