Vaisala DSC211 – Contactless Remote Sensor for Road Conditions

Detect ice, water, and snow from a distance without interfering with the road surface. Vaisala DSC211 uses advanced laser technology to measure road conditions and friction from a pole – the perfect solution for bridges and runways where operational safety is critical.

Vaisala DSC211 sets a new standard for non-contact road surface measurement. Using spectroscopic laser technology, the sensor can identify exactly what is covering the road surface from up to 15 meters away. It accurately distinguishes between dry road surfaces, moisture, water, ice, slush and snow.

The advantage of the DSC211 compared to traditional sensors is that it does not require any costly installations in the asphalt itself. This eliminates the risk of damage during plowing or paving and makes maintenance extremely easy. The sensor also calculates the road surface friction in real time, which provides an objective basis for decision-making for skid control. Thanks to its ability to measure the thickness of the water film, it can also warn of the risk of aquaplaning on busy roads and airports.
Technical specifications

Areas of use

Bridges & Viaducts: Since bridges freeze before surface roads, the DSC211 is ideal for providing early warnings without weakening the bridge structure with recessed sensors.

Airports (Runway Safety): Measure friction and hydroplaning risk on runways in real time to optimize safety during takeoffs and landings.

Critical Road Sections: Monitor accident-prone curves or steep slopes where rapid weather changes require immediate action from the road operator.

Industrial areas & Ports: Secure logistics flows by having full control over the risk of slipping in terminal areas without disrupting heavy traffic during installation.
