The Model 03002 Wind Sentry Anemometer
and Vane are professional quality sensors suitable for a wide range of wind
measurement applications. These economically priced sensors provide excellent
sensitivity, corrosion resistance, and minimal parts count for easy
maintenance.
The anemometer uses three lightweight hemispherical cups to measure wind speed.
Cup wheel rotation produces an ACfrequency 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.
