Vaisala Present Weather Sensor FS11P

Traceable visibility measurement and precipitation type detection Runway visual range (RVR), aeronautical and synoptical visibility and present weather observation for demanding weather applications. Features  • Detects precipitation type and intensity  • Well suited for synoptic​ and aeronautical applications  • The most widely proven forward scatter RVR sensor, selected and used by FAA  • Meets FAA and ICAO specifications for RVR and visibility measurement  • The most widely proven present weather sensing technology  • Meets ICAO frangibility standards Key Benefits • Excellent value   • RVR, visibility and present weather all-in-one. Measures visibility up to 75 km.  • Minimal look-down geometry   • The second is "head-down" design of the optical heads, which protects them against virtually all windblown particles (even those flying horizontally).  • Reliability   • Four main design features (e.g.an optical path clearance monitoring circuitry) are combined in the FS11P to ensure reliable operation in the harshest weather.
