WDA wind direction

What is and what is used for

The axis of the weather vane moves on a set of ball bearings and is equipped with a magnet on one of the two ends. The relative angle of the weather vane is scanned by a contactless angular magnet sensor that returns a voltage depending on the relative position between magnet and sensor. From here a microcontroller calculates the direction of the wind, linearising the ratio between angle and output current.

Construction

The WDA gonioanemometric transducer is designed to acquire the direction of the horizontal component of wind, and returns an analogue electrical output proportionate to the measured value.
