Patent ID: RE42057

Claim:
A weather station with at least one element mounted on bearings on a housing or rack on a vertical axis for alignment with the direction of the wind and with a measuring device, which depending on the angle position of the element aligning in the direction of the wind provides an electrical signal, wherein the measuring device comprising an opto electric measuring device with at least two light paths, each of which has its own light-emitting element and which have a common light detector and form a light path configuration, each light path is used to scan a group of markings, which are located around an axis of at least one screen in such a manner that the markings provide a code when scanning that defines the angle area of the position of the element aligning with the direction of the wind, the at least one screen and the light path configuration corresponding to the position of the element aligning with the direction of the wind can be swivelled relative to each other around the axis of the screen, and an electronic control and analysis unit is provided that individually activates the light-emitting elements during a measuring or analysis phase and hereby determines the angle position of the element aligning with the direction of the wind.
