Transport Meteorology - Automobile & Ground Transport - Cars

The Biral sensors provide reliable, consistently accurate weather information day and night. This allows timely decisions to be made about spraying or gritting road surfaces and for switching road warning signs, achieving the best results from limited and valuable resources. In addition to the visibility and present weather sensors, Biral are the appointed UK Distributor for the meteorological instrument manufacturer, Adolf Thies GmbH & Co. KG. The Thies Clima range of meteorological sensors is highly respected and used globally in many advanced meteorological applications. It offers a complete and complimentary range of sensors allowing a highly specified meteorological monitoring station or system to be constructed. The range includes cup and vane and ultrasonic anemometers, temperature, humidity, pressure and radiation sensors, as well as a wide range of compact weather stations and precipitation sensors.

Getting the information needed at the time it is needed and in a format that makes the decision making process quick and simple requires accurate sensors located in the most suitable locations.

 

Biral visibility and present weather sensors are especially well suited to this application where the combination of serial and analogue interfaces allow both local signage control and direct connection to a wider network.  The ability to provide present weather information in addition to visibility allows intelligent transport systems (ITS) to not only ensure that the road users have the most accurate information but also allows planned maintenance activities such as salt spreading or sand clearance.

 

Visibility sensors are used in tunnels where they monitor pollution levels and control ventilation systems. Visibility sensors can also assist with the detection of fire in tunnels due to their sensitivity to smoke particles.  The compact forward scatter design and the availability of 4-20mA signalling makes the SWS-050T particularly suited to this application.

 

Biral sensors are used in single installations or multiple sensor networks and are used world-wide. They are in operation 24/7 in many safety critical applications in transport project on major roads, bridges and in tunnels.

 

Use Biral Sensors to Improve Safety

Sensors are typically installed within 3m of the roadside and measure the local weather conditions (fog, snow, rain, spray, and related parameters).

 

The information provided by the sensors is easy to understand and integrates into any control system.  The sensors can switch a local warning sign via a relay and / or transmit the data via a second output to an ITS regional control centre.
