YOUNG MECHANICAL WIND SENSOR

The Wind Monitor is a high performance wind sensor. Rugged, corrosion-resistant construction makes it ideal 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. The wind direction sensor is a rugged yet lightweight vane. Vane angle is sensed by a precision potentiometer. Constructed of UV stabilized plastic with stainless steel and anodized aluminum fittings, the sensor mounts on standard 1 inch pipe.
