Wind sensors: wind vanes

Wind Vanes

Wind vanes determine wind direction. Evaluation of the wind direction enables the best possible positioning of wind turbines. Ammonit wind vanes offer an excellent, fine resolution of 1°, while having very low energy consumption. It is essential that a wind vane covers an entire 360° degree radius, without a north gap. Cheaper wind vanes often have lower quality internal electro-mechanic fittings, which limit their life span, and a considerable north gap. Most wind vanes can be equipped with electronically regulated heating. Analog or potentiometric wind vanes are available.
