Senseca has recently released the RWS-20 road weather sensor. The RWS-20 is a forward scatter visibility sensor designed specifically for road applications where accurate and reliable visibility measurements are essential. Its measurement principle and robust optical design are intended to provide stable performance in all weather conditions and are not affected by local light sources such as vehicle headlights, flashing signs or warning beacons.

With a measurement range from 10 m to 7.5 km, the RWS-20 is optimised for situations where fog, heavy rain, surface spray and snow can significantly reduce visibility and compromise driving safety. Heated optical windows and sensor hoods support operation in winter conditions, while continuous contamination monitoring and automatic compensation minimise maintenance effort.

The performance of the RWS-20 is comparable to that of a transmissometer, with calibration carried out in accordance with ICAO 9328 and traceable to an independent national weather service transmissometer.
