Present Weather Sensor

DESCRIPTION

Biral visibility and present weather sensor. Visibility range: 10m ÷ 50km (selectable full scale 2km, 10km, 20km, 32km or 50km), recognizing the type and amount of precipitation (presence of fog, haze, smoke, sand, drizzle, rain, snow and precipitation). This sensor has features of disdrometer and visibility measuring in a compact solution. Infrared measuring principle with distinction of phenomena according to WMO regulations reference table 4680 and 9328 ICAO standard. Out standard: RS485 (with heater option available and analogical output). This sensor is suitable for applications in various fields of environmental monitoring, and is particularly suitable for the AWOS weather stations in the aeronautical field. Easy to install, requires no periodic calibration and is protected from overvoltage and corrosive agents. The sensor is designed for mounting on pole by two collars adjustable (included).
