The Wind Speed Wind Direction Sensor – Model 5712-00 is a rugged, accurate wind sensor. The simple, lightweight corrosion-resistant construction makes the Wind Speed Wind Direction Sensor well suited for a wide range of wind measurement applications.
The Wind Speed Wind Direction Sensor uses a four blade helicoid propeller. The Wind Speed Wind Direction Sensor’s propeller rotation produces an AC voltage signal with a frequency directly proportional to wind speed. Slip rings and brushes are not used resulting in improved reliability and lower cost.
The wind direction sensor is a rugged, lightweight vane with a low aspect ratio to assure good fidelity in fluctuating wind conditions. The Wind Speed Wind Direction Sensor’s vane angle is sensed by a precision potentiometer housed in a sealed chamber. With a known excitation voltage applied to the potentiometer, the Wind Speed Wind Direction Sensor’s output signal is directly proportional to azimuth angle. An orientation ring is supplied for preserving wind direction reference when the Wind Speed Wind Direction Sensor is removed for maintenance.
