RM Young 05103 Wind Monitor


The 05103 RM Young Wind Monitor is a high performance, rugged combined wind speed and direction sensor. Its simplicity and corrosion-resistant construction make it ideal for a wide range of wind measuring applications


  • Propeller-type anemometer with fuselage and tail wind vane
  • Rugged design for use in a variety of climates worldwide
  • Models available for offshore and marine use or with alternative voltage or 4-20mA output

Wind Speed

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.

Wind Direction

The wind direction sensor 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.

Construction and Mounting

The instrument 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. The 05103 mounts directly on a 1.0 inch IPS Schedule 40 (1.32 inch O.D.) pipe. Campbell Scientific supplies a 10-inch pipe for mounting the Wind Monitor as part of the 019WM Crossarm. An alignment ring maintains wind direction reference orientation during maintenance.
