Product Description

The Wind Monitor Alpine measures horizontal wind speed and direction. We recommend this sensor for wind resource assessment when icing is a problem and heated sensors are not an option.

This sensor is rugged and corrosion resistant, yet accurate and light weight. Its simplicity and corrosion-resistant construc­tion make it ideal for a wide range of wind measuring applica­tions. The external housing surfaces of YOUNG ALPINE 05103-45 are coated with a special ice resistant coating to improve performance in harsh alpine conditions.

Both the propeller and vertical shafts use stainless steel preci­sion grade ball bearings. The instrument mounts on standard pipe, outside diameter 34 mm.
