Precision Wind Sensor
Cobwebs could eventually block an anemometer wheel during calm periods. However, the Tecnautic Wind Sensor has a little motor inside, that will free it automatically, every time power is turned on.
During normal operation, the motor is delivering just enough torque, to compensate for the bearing friction, thus effectively eliminating any drag.
The wind angle is sensed with a wedge shaped vane, providing higher accuracy than a single vane. The resulting data are so accurate, that the angle can be measured with a resolution of 0,3 degrees.
The Sensor has ball bearings for wind speed and wind angle and has virtually no wear.
