Wind Sentry
Model 03002/03102
The anemometer uses three lightweight hemispherical cups to measure wind speed. Cup wheel rotation produces an AC frequency that is linearly proportional to wind speed. The vane employs a balanced vane assembly with vane position sensed by a long life precision potentiometer. Precision stainless steel ball bearings are used throughout.
For wind speed only, Model 03102 Wind Sentry Anemometer is available separately.
