RWS-20 Road Weather Sensor

The RWS-20 Road Weather Sensor is designed for use in road applications where accurate and reliable visibility measurements are required. The forward scatter measurement principle and unique design ensure the output is both accurate and reliable in all weather conditions and will not be influenced by local light sources, even flashing signs.

The 10m to 7.5km measurement range is optimal for use in road applications.  Heating of the optical windows prevents misting and the optional sensor hood heating can be provided, allowing use in the harshest of conditions. Both optical windows are monitored for contamination and the visibility output is automatically compensated to reduce maintenance requirements.

In addition to the serial data interface, the sensor provides analogue voltage output and optional current outputs of visibility (MOR) or extinction coefficient (EXCO). Optional relays provide threshold and self-test switching capability.
