Obtaining information concerning external conditions at a wind turbine

摘要

A device (310) for obtaining information concerning at least one external condition at a wind turbine (100) is provided, comprising
at least one capture element (320) suitable for being fixed at an upwind side of a rotor plane (140) of the wind turbine (100), wherein
- the at least one capture element (320) comprises at least one channel (321)
- with at least one opening (322) for obtaining the information at the upwind side of the rotor plane (140),
- a part (333) of the channel (321) with the at least one opening (322) substantially points towards a downwind direction (141) of the wind turbine (100),
- a longitudinal axis (340) of the part (333) of the channel (321) is substantially parallel to a rotation axis (142) of the rotor plane (140). Further, a device and a wind turbine are suggested.
