The YOUNG Model 05108 Wind Monitor-HD measures horizontal wind speed and direction. This sensor has many of the same features as Model 05106, including long-lasting, corrosion resistant, ceramic bearings and a ¼ inch diameter propeller shaft. It features a high pitch propeller that will extend bearing longevity due to its lower rotation rate at like wind speeds. The direct output for wind speed is an AC sine wave and direction is a precision potentiometer. The sensor mounts on a standard 1-inch IPS pipe.
