General Description

Model 05305 Wind Monitor-AQ is a high performance wind speed and direction sensor designed specifically for air quality measurements, but is less rugged than the 05103. The Wind Monitor-AQ features low starting threshold, fast response, and high accuracy.

Wind Speed
The wind speed sensor is a helicoid-shaped, four-blade propeller. Rotation of the propeller produces an AC sine wave; the frequency is directly proportional to the wind speed. The AC signal is induced in a transducer coil by a six-pole magnet mounted on the propeller shaft. The coil is located on the non-rotating central portion of the main mounting assembly, eliminating the need for slip rings and brushes.

Wind Direction
Wind direction is sensed by a potentiometer. With the precision excitation voltage from the datalogger applied to the potentiometer element, the output signal is an analog voltage directly proportional to the azimuth angle.

Construction and Mounting
Construction is of rigid UV-stabilized thermoplastic with stainless steel and anodized aluminum fittings. Propeller shaft bearings and vertical shaft bearings are stainless steel precision-grade ball bearings. The 05305 mounts directly on a 1.0 inch IPS Schedule 40 (1.32 inch O.D.) pipe. Campbell Scientific supplies a 10-inch pipe for mounting the Wind Monitor to the 019WM Crossarm. An alignment ring maintains wind direction reference orientation during maintenance.
