Visibility sensor
Measures atmospheric visibility PCTVI006 (meteorological optical range) by determining the amount of light scattered by particles (smoke, dust, haze, fog, rain, & snow) in the air that pass through the optical sample volume.
42-degree forward scatter angle is used to ensure performance over a wide range of particle sizes. MOR is calculated by converting the received signal strength (extinction coefficient, σ) using Koschmeider’s formula, MOR (Km) = 3/σ.
Performance in all weather conditions is achieved with an integrated sensor design that keeps all sensor cabling internal to the sensor for complete protection against the weather.
