Air Quality Wind Monitor

Campbell Scientific

The 05305 is a lightweight, high-performance wind-speed and wind-direction sensor designed specifically for air-quality measurements. It is more responsive but less rugged than the other wind monitors.

The 05305 Wind Monitor-AQ is made out of light-weight, UV-stabilized thermoplastic with stainless steel and anodized aluminum fittings. The thermoplastic material resists corrosion from sea air environments and atmospheric pollutants. It uses stainless-steel precision-grade ball bearings for the propeller shaft and vertical shaft bearings.

The 05305 measures wind speed with a helicoid-shaped, four-blade propeller. Rotation of the propeller produces an ac sine wave that has a frequency directly proportional to wind speed. The ac signal is induced in a transducer coil by a six-pole magnet mounted on the propeller shaft. The coil resides on the non-rotating central portion of the main mounting assembly, eliminating the need for slip rings and brushes.
