The R M Young Model 05103L Young Wind Monitor is one of our high performance and rugged wind direction sensors that features two 4-20mA outputs. The simplicity of the Young Wind Monitor and corrosion resistant construction make 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 with frequency directly proportional to wind speed. Slip rings and brushes are eliminated for increased reliability.

Compared to ordinary wind direction sensors, the sensor in this Young Wind Monitor is a rugged, yet 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 voltage 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.

The Young Wind Monitor is made of UV stabilized plastic with stainless steel and anodized aluminum fittings. Precision grade, stainless steel ball bearings are used. Transient protection and cable terminations are in a convenient junction box on the mounting post. The instrument mounts on standard 1 inch pipe.

Two 4 to 20mA outputs are provided (one for wind speed and one for wind direction). These outputs are used by process control and SCADA systems.
