The 03002 measures wind speed and direction with a 3-cup anemometer and a wind vane mounted on a small crossarm. The small size, simplicity, and rugged construction provide a quality instrument for a modest price. The sensor interfaces directly with Campbell dataloggers; no signal conditioning is required.
Features
The 03002 Wind Sentry Set consists of a 3-cup anemometer and a wind vane mounted on a small crossarm. The small size, simplicity, and rugged construction provide a quality instrument for a modest price. The sensor interfaces directly with Campbell dataloggers; no signal conditioning is required.
Rotation of the Wind Sentry's cup wheel produces an ac sine wave that is directly proportional to wind speed. The frequency of the ac signal is measured by a datalogger pulse count channel, then converted to engineering units (mph, m/s, knots). The Campbell Scientific version uses shielded bearings, which lower the anemometer's threshold.
Wind direction is sensed by a potentiometer. With the precision excitation voltage from the datalogger applied to the potentiometer element, the output signal is an analog voltage that is directly proportional to azimuth of the wind direction.
