The NIRS31-UMB is a non-invasive road weather sensor with optical measuring principle. It is mounted at masts or bridges up to 50 ft distance to the measurement spot on the road and can even monitor bridges. It measures surface conditions such as surface temperature, wetness, ice, snow, or frost as well as water film heights and calculates additional parameters like ice percentage in water, freeze point temperature and generates the friction coefficient on the road.
The optical (spectroscopic) measuring principle delivers the important road surface condition parameter without the need of construction works on the road itself.
Road condition is evaluated over a representive spot area of the road surface of >2 sqm.
Sensor measures on multiple wavelengths in the infrared optical range and delivers important road information: surface temperature, water film height, ice layer thickness, ice percentage, freezing temperature, road condition index, friction and snow height.
