OTT/Lufft Road Sensor NIRS31-UMB

non-invasive road weather sensor with optical principle

The NIRS31-UMB is a non-invasive road weather sensor working with optical principle and is mounted several meters above the surface at bridges or masts. It measures surface conditions such as wetness, ice, snow, or frost as well as water film heights, ice percentage in water and freeze point temperature. Through these measurements it generates the friction coefficient on the road or runway.
