Optically-scanned cup anemometer
Thies First Class Advanced gives outstanding performance. The sensor has been classified acc. to IEC 61400-12-1 Edition 2.0. It gives optimal dynamic performance with the following characteristics:
The sensor is designed for measuring the horizontal wind velocity in the field of meteorology, climate research, site assessment, and the measurement of capacity characteristics of wind power systems (power curves). The patented design is the result of long testing in the wind tunnel. The sensor features dynamic behaviour also at high turbulence intensity, minimal overspeeding, and a low starting values. It requires only low maintenance thanks to its low-inertia and ball-bearing cup star. The anemometer is equipped with electronically regulated heating to guarantee smooth running of the ball bearings and prevent icing of shaft and slot during winter operation.
