Present Weather Sensor FS11P

RVR, visibility and present weather all-in-one. Measures visibility up to 75 km.

The second is "head-down" design of the optical heads, which protects them against virtually all windblown particles (even those flying horizontally).

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.
