5] SCIENTIFIC WHEN MEASUREMENTS MATTER Overview The 03002, manufactured by R. M. Young, measures wind speed and direction with a 3-cup anemometer and a wind vane mounted on a small crossarm. It interfaces directly with Benefits and Features ) Compatible with most Campbell Scientific data loggers ) Designed for continuous, long-term, unattended operation in adverse conditions ) Small size, simplicity, and rugged construction provide a quality instrument for a modest price ) Ideal for wind profile studies Technical Description The 03002 uses a cup wheel assembly to measure wind speed. Rotation of the 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). Campbell Scientific's version uses shielded bearings, which lowers the anemometer's threshold. Specifications Applications General (Rain with light snow. Little or no riming or blowing sand. No salt spray.) Sensor 3-cup anemometer and vane @ [ ([o8tchi= 03002 Wind Sentry Set Reliable, Competitively Priced Good all purpose wind set Campbell Scientific dataloggers; no signal conditioning is required. ) Compatible with the LLAC4 4-channel Low-Level AC- Conversion Module, which increases the number of anemometers one data logger can measure ) Campbell Scientific version uses shielded bearings, which lowers the anemometer's starting threshold ) Compatible with the CWS900-series interfaces, allowing it to be usedin a wireless sensor network 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 the azimuth angle of the wind direction.
