Launched in 2008, the NIRS31 was Lufft’s first non-contact road weather sensor that allows easy installation without road closures and costly construction work. It is therefore particularly suitable for the use on bridges where the installation of embedded ground probes entails structural risks. As bridges are usually exposed to stronger winds and the cooling and evaporation of the underlying water it makes sense to monitor them thoroughly.
The NIRS31 was also the base for the development of the mobile sensor MARWIS and the latest stationary sensor with a lower installation height StaRWIS. Reason enough to dedicate this contribution to this sensor – with the best references!
