The SWS-200 combines a proven forward-scatter geometry with an additional backscatter receiver to measure Meteorological Optical Range (MOR) and report present weather with greater confidence—especially during mixed or rapidly changing precipitation. By analysing signals from both channels, it improves separation between liquid and frozen precipitation, supporting more dependable reporting for operational networks.
The sensor’s default visibility range is 10 m–20 km, while the maximum range can be user-configured up to 99.99 km via a simple configuration command. Visibility can be delivered at 1 m or 10 m resolution, making it suitable for both detailed near-field monitoring and stable network reporting.
Designed for continuous outdoor operation with minimal servicing, the SWS-200 includes hood heating, window contamination monitoring with automatic correction, and built-in status/self-test functions to help maintain data quality over time. Standard serial interfaces simplify integration, and an optional board slot expands connectivity for specific system needs (e.g., RVR or legacy I/O).
