Description:
The R.M. Young 05103 Wind Monitor is a high performance rugged wind sensor. Its simplicity and corrosion resistant construction make it ideal for a wide range of wind measuring applications. These wind speed meters use 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.
The R.M. Young 05103 Wind Monitor has 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 R.M. Young 05103 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. These wind speed meters mount on a standard 1 inch pipe.
