| Measurement Range | Wind Speed/Gust: 0 to 76 m/s (0 to 170 mph) Wind Direction: 0 to 355 degrees, 5 degree dead band |
|---|---|
| Accuracy | Wind Speed/Gust: ± 1.1 m/s (2.4 mph) or ± 4% of reading whichever is greater Wind Direction: ± 5 degrees |
| Resolution | Wind Speed/Gust: 0.5 m/s (1.1 mph) Wind Direction: 1.4 degrees |
| Starting Threshold | Wind Speed/Gust: 1.0 m/s (2.2 mph) Wind Direction: 1.0 m/s (2.2 mph) |
| Measurement Definition | Wind Speed/Gust: 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. Wind Direction: Unit vector averaging used; vector components for each wind measurement are calculated every three seconds for duration of logging interval (see Measurement Operation) |
| Operating Temperature Range | Wind Speed/Gust: -40°C to +75°C (-40°F to +167°F) Wind Direction: -40°C to +70°C (-40°F to +158°F) |
| Environmental Rating | Weatherproof |
| Housing | Wind Speed/Gust: Three cup polycarbonate anemometer: Modified Teflon® bearings and hardened beryllium shaft with ice shedding design Wind Direction: Injection-molded housing and vane, static dissipating base, lead-free silicon bronze nose, and aluminum mounting rod. |
| Bearing Type | Wind Speed/Gust: Modified Teflon® bearings Wind Direction: two shielded stainless steel ball bearings |
| Turning Radius | Wind Speed/Gust: 9.5 cm (3.75 in.) Wind Direction: Approximately 13.5 cm (5.25 in.) |
| Dimensions | Wind Speed/Gust: 41 x 16 cm (16 x 6.5 in.) including 1.27 cm (0.5 in) diameter mounting rod; 5.5 cm (2.1 in.) drip overhang Wind Direction: 46 x 20 cm (18 x 8.5 in) including 1.27 cm (0.5 in) diameter mounting rod, 2.5 mm (0.1 in) drip overhang |
| Weight | Wind Speed/Gust: Approximately 700 g (1.5 lbs) Wind Direction: Approximately 370 g (13 oz) |
| Service Life | Wind Speed/Gust: Greater than 5 years typical Wind Direction: 4 to 6 years typical depending upon environmental conditions |
| Number of Data Channels* | Wind Speed/Gust: 2 Wind Direction: 1 |
| Measurement Averaging Option | Wind Speed/Gust: No Wind Direction: Automatic averaging (see Measurement Operation) |
| Cable Length Available | 3.5 m (11.5 ft) |
| Length of Smart Sensor Network Cable* | 0.5 m (1.6 ft) |
HOBO Wind Speed and Direction Set Smart Sensor
Overview
The Wind Sensor Set includes Onset’s research-grade plug-and-play Wind Speed Smart Sensor and the Wind Direction Smart Sensor. This combination provides average wind speed, highest 3-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.
