The Biral RWS-20 Road Weather Sensor is a highly reliable, compact device designed for real-time monitoring of road surface conditions. It measures key parameters such as surface temperature, surface state (dry, wet, icy, snowy), water film height, freezing point temperature, and road friction coefficient to provide critical data for road safety and traffic management applications. The sensor uses non-invasive optical measurement technology for accurate detection of road surface conditions without direct contact with the pavement, ensuring long-term durability and low maintenance. It features digital signal output options such as RS485 and CAN for seamless integration with traffic management systems. The RWS-20 is supplied with a standard cable length of up to 10 meters, with optional extensions available to suit site requirements. This sensor is widely used by highway authorities, meteorological stations, and intelligent transport systems to enhance decision-making during adverse weather conditions.
