Gill WindObserver 65 is a high-precision ultrasonic wind sensor with a rugged construction, providing accurate wind speed and direction data via digital output. The sensor features a stainless steel housing rated to IP66, making it especially suitable for saline environments such as coastal and offshore areas.
This wind sensor includes an optional de-icing system, enabling reliable operation under harsh environmental conditions such as high altitudes or offshore installations. It is recommended for use in aviation, maritime, and offshore applications.
Users can select sliding vector averaging and 3-second gust measurements in accordance with the guidelines of the World Meteorological Organization (WMO – No. 8, 7th Edition, 2008, ISBN 978-92-63-10008-5).
