Accurate weather observation data for runway visual range, aeronautical, and synoptical applications.
Vaisala sensors FS11 and FS11P are forward scatter sensors that can be used in the most demanding weather situations. The
FS11 measures visibility, while the FS11P additionally measures present weather.
Both sensors provide accuracy, reliability, broad measurement range, and low maintenance in weather applications such as runway visual range (RVR), aeronautical and synoptical visibility, and present weather observation.
To ensure reliable operations — even in the harshest weather conditions — the FS11 and FS11P utilize four main design features:
Designed according to ICAO, FAA, and WMO guidelines, the FS11 is an ideal instrument for runway visual range (RVR) assessment and airport visibility measurement, as well as other demanding applications. It provides the optimal combination of the best accuracy, the highest reliability, broad measurement range, and low maintenance needs.
The FS11P offers traceable visibility measurement and precipitation type detection for runway visual range (RVR), aeronautical and synoptical visibility, and present weather observation for demanding weather applications.
The sensor is designed to detect precipitation type and intensity and is the most widely proven forward scatter RVR sensor that is selected and used by the FAA. Additionally, it is the most widely proven present weather sensing technology.
