|Definition||A forward-scattering visibility sensor designed to monitor visibility and obstruction to vision caused by dust, fog, rain, drizzle, snow and hail. It includes digital, analogue and switching relay outputs. It features WMO 4680 precipitation codes, and measurements are reported as instantaneous and averaged forward scatter Meteorological Optical Range (MOR). Reporting of atmospheric Extinction Coefficient (EXCO) is a user selectable option. The sensor enclosure is aluminium as standard, a powder coating to protect from corrosion. It can be supplied with a hard coat anodizing and powder coat finish as an option, recommended for marine environments. Heated hoods are also available. It uses RS-485 Modbus communication. Default measurement range is 10 - 2000 m, with maximum visibility ranges up to 75 km and a user selectable resolution of either 1 or 10 m. The scatter angle ranges from 39 to 51 degrees, centred at 45 degrees. Operating temperature is from -40 to +60 degC.|
