Wind Speed and Direction Smart Sensor

Part # S-WCA-M003
 
This product is discontinued.
 

Upgrade to S-WSET-A

Overview

The combination Wind Speed and Direction Smart Sensor 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, the Wind Speed/Direction Smart Sensor offers high accuracy at an affordable price. The wind speed sensor 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:

  1. on tall buildings
  2. in the wake of  wind turbines or other locations with turbulence
  3. 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.

Specifications Wind Speed/Gust Wind Direction
Measurement Range 0 to 44 m/s (0 to 99 mph) 0 to 358 degrees, 2 degree dead band
Maximum Wind Speed Survival In non-icing conditions: 45 m/sec (100 mph) peak, or 34 m/sec (75 mph) sustained*

 

In icing conditions: 34 m/sec (75 mph) peak, or 18 m/sec( 40 mph) sustained*

Accuracy ± 0.5 m/s (± 1.1 mph) ± 3% 17 to 30 m/s (38 to 67 mph) ± 4% 30 to 44 m/s (67 to 99 mph) ± 5 degrees
Resolution 0.19 m/s (0.42 mph) 1.4 degrees
Starting Threshold 0.5 m/s (1.1 mph) 0.5 m/s (1.1 mph)
Damping Ratio NA 0.4
Distance Constant Approximately 3 m (9.8 ft) 0.8 m (2.6 ft)
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.
Operating Temperature Range -40°C to +75°C (-40°F to +167°F)
Environmental Rating Weatherproof
Service Life 2 to 5 years typical depending upon environmental conditions
Housing Anodized aluminum housing, injection-molded plastic cups, stainless steel fasteners, Acetal base, and black anodized aluminum mounting rod.
