The Wind Monitor is a high performance, rugged
wind sensor, its simplicity and corrosion-resistant construction make it idea for a wide range of wind measuring
applications
The wind speed sensor is a four blade helicoid propeller. Propeller rotation produces an AC sine wave voltage signal with a frequency directly proportional to wind speed. Slip rings and brushes are eliminated resulting in increased reliability and lower cost
The wind direction sensor is a rugged test lightweight vane with a sufficiently low aspect ratio to assure good fidelity in fluctuating wind conditions. Vane angle is sensed by a precision potentiometer housed in a sealed chamber. With a known excitation voltage applied to the potentiometer, the output is directly proportional to vane angle. A mounting orientation ring assures correct realignment of the wind direction reference when the instrument is removed for maintenance
