NIRS31-UMB Road Condition Sensor
Key Benefits
- Non-intrusive — no road surface contact or in-pavement installation
- NIR spectroscopy for precise surface state classification
- Detects dry, moist, wet, icy, snowy, slushy and frost conditions
- Measures water film height, ice percentage and salinity
- UMB (Universal Measurement Bus) interface for easy integration
- Robust design for long-term unattended roadside deployment
Primary Specifications
Surface Condition Classification
The NIRS31-UMB classifies the road surface into the following states in real time, enabling targeted maintenance and safety alerting.
Where It's Used
Fixed RWIS Stations
Permanent highway road weather stations for motorway safety networks.
Bridges & Overpasses
Ice detection at frost-prone elevated structures where conditions differ from surrounding roads.
Airport Runways
Non-intrusive runway condition assessment for aviation safety compliance.
Winter Maintenance
Targeted anti-icing and de-icing dispatch based on real-time surface state data.
UMB Integration
The NIRS31-UMB uses Lufft's Universal Measurement Bus (UMB) protocol — a standardized serial interface that allows seamless integration with Lufft compact weather sensors (WS800 series), dataloggers and third-party RWIS controllers.
- Compatible with Lufft WS800 compact weather sensor
- Integrates with standard RWIS data acquisition systems
- NTCIP-compliant outputs available
- Data feeds into IES WebGIS for road condition mapping
