Weather sensor RWS-30

The RWS-30 Road Tunnel Weather Sensor is designed for use in road and tunnel applications where accurate and reliable visibility measurements are required. Application: Roads and Transport The RWS-30 Road Tunnel Weather Sensor is designed for use in road and tunnel applications where accurate and reliable visibility measurements are required. The forward scatter measurement principle provides a compact design with measurements that are both accurate and reliable in all weather conditions. The RWS-30 outputs have been chosen to match those recommended for use in tunnel systems. Applications As road networks become more congested those tasked with the management of traffic flow and road user safety are turning to Road Weather Information Systems (RWIS) to collect meteorological data they need. Road tunnels pose a unique set of problems as they are affected by the weather at either end and can have their own internal microclimates. Couple this to the added risk of pollution from stationary vehicles or fire after a crash and the need for a sensitive and accurate sensor to measure visibility becomes essential. The RWS-30 has been developed to meet the specific needs created by the tunnel environment and complies with current international guidelines as defined by the PIARC Technical Committee. Tunnel Safety Visibility sensors, especially those with an extended visibility range, can act as sensitive pollution monitors allowing the ventilation systems to be activated before pollution increases to dangerous levels. Visibility sensors can also form part of a fire detection system by detecting a sudden and isolated visibility decrease.
