HOBO Wind Speed and Direction Set Smart Sensor

SKU: S-WSET-B

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.

What measurements does this sensor support?

The S-WSET-B sensor supports the following measurement: Wind

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
