The 03101 Anemometer is for applications that need only wind speed measurements, not wind direction measurements. This cup anemometer accurately measures wind speed. 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 its 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 lowers the anemometer's threshold.
