Multi Wind Sensor

Campbell Scientific

The 03002 wind sensor measures wind speed and direction with a 3-cup anemometer and a wind vane mounted on a small crossarm. It interfaces directly with Campbell Scientific dataloggers; no signal conditioning is required. 

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). The 03002 version uses shielded bearings, which lowers 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 the azimuth angle of the wind direction.
