Alpine

　　Wind Monitor

　　Ice-resistant

　　Model 05103-45

　　The Wind Monitor – ALPINE MODEL offers the performance and rugged construction of our standard Wind Monitor with the added benefit of an ice-resistant coating on external surfaces. It promises improved survivability for the most severe wind measuring applications.

　　The wind direction sensor is a rugged molded vane. The wind speed sensor is a four blade helicoid propeller. Propeller diameter is slightly reduced from our standard model to minimize vibration at high speeds. External housing surfaces are coated with a specially formulated, Ice-resistant coating to improve performance in harsh alpine conditions. The all-black color scheme further enhances ice-shedding performance of the sensor. The instrument is made of UV stabilized plastic with stainless steel and anodized aluminum fittings. The instrument mounts on standard 1 inch pipe. Model 05103V-45 offers calibrated voltage outputs, Model 05103L-45 provides 4-20 mA current outputs.
