Wind Sentry Anemometer

Campbell Scientific

The 03101 is the three-cup anemometer included with our Wind Sentry Sets. It can be purchased separately for applications that require only wind speed measurements. The 03101 connects directly to a datalogger, which measures the anemometer's pulse signal and converts the signal to engineering units (mph, m/s, knots). The 03101 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.
