New Road Weather Sensor Launched by Biral

Posted on 18th January 2017 in News

Meteorological equipment specialists Biral, has just launched a very competitively priced new Road Weather Sensor (RWS-20) to monitor visibility and obstruction to vision for road transport applications.


Biral manufactures high quality meteorological sensors for professional markets, and its new product has been designed for use in road applications to provide reliable visibility measurement data. The sensor has been manufactured to allow easy integration with any Road Weather Information System (RWIS).

The RWS-20 has been specifically developed for the harsh road-side environment and is based upon the proven and very successful SWS range of visibility sensors, sharing many of its advanced technical features.

The new design is a compact forward scatter measurement principle and remains accurate in all weather conditions, ensuring local light sources, headlights or flashing signs do not impact its operation or reliability.

The RWS-20 has a measurement range of 10m to 7.5km, for use in road applications where fog, rain, spray and snow can create dangerous driving conditions. The optical windows and sensor hoods contain heating for use in harsh weather conditions throughout the year. Both optical windows have systems for lens contamination monitoring, ensuring the visibility output is constantly compensated to maintain accuracy whilst reducing routine maintenance duties.

In addition to monitored window heating, Biral’s new Road Weather Sensor has a 2 year warranty and self-test capabilities, along with automatic alerts for cleaning the optical windows. The product has a serial data output of RS232, RS422 or RS485, while providing analogue voltage visibility outputs (0-10V) or the extinction coefficient (EXCO).

The RWS-20 also features optional relays which can directly connect to road-side signage and other control systems, allowing intelligent communication and operation of local warning signs. This new addition to Biral’s Weather Sensor range is easily integrated into any Road Weather Information System (RWIS) to create a complete meteorological monitoring system.
