HIM-Electronic and conventional sensors and devices for determining wind direction

A wind direction sensor, also called a wind vane, weather vane or, to a limited extent, an anemoscope, is an indicating instrument for determining the wind direction. It is based on the fact that a movable measuring element aligns itself with the dynamic pressure of the wind.

A wind direction indicator can be regarded as a static system with only one mechanically stable state of equilibrium. The flag surface, which is arranged asymmetrically to the axis of rotation and on which the wind exerts a torque if it is not aligned parallel to the wind direction, serves as the input element. The wind direction sensor itself again serves as the output element, since its orientation in wind corresponds to its direction (cf. also directional stability).
