South Col Anemometer

In 2008 at South Col the CombiSD DNA022 sensor (LSI-Lastem, Italy) was installed. During the 2011 expedition, this sensor was replaced with a prototype (LSI-Lastem) to support with another sensor manufactured by VAISALA: WA15D7B.

The WA15 is based on accurate sensors installed on a large crossarm. It is designed for demanding wind measurement applications. Three lightweight, conical cups mounted on the cup wheel, provide excellent linearity over the entire operating range, up to 75 m/s.

A wind-rotated chopper disc attached to the shaft of the cup wheel cuts an infrared light beam 14 times per revolution. This generates a pulse output from the phototransistor. The output pulse rate is directly proportional to wind speed (e.g. 246 Hz = 24.6 m/s). However, for the highest accuracy, the characteristic transfer function should be used to compensate for starting inertia.
