For stationary operations Lufft developed the StaRWIS. This sensor has been developed, based on the innovation award-winning mobile road weather sensor MARWIS.
StaRWIS is the first non-invasive road weather sensor, detecting road and runway surface conditions, surface temperatures, relative humidity, dew & freezing temperatures, ice percentages, as well as non-invasively friction. Its 4 lenses are based on innovative LED technology.
Road condition (dry, moist, wet, ice, snow, critical wet, chemically wet), road surface temperature, ambient temperature, water film height, dew point temperature, relative humidity, ice percentage, freezing temperature, friction (calculated)
Optical LED transmitters, photo receivers, pyrometer, infra-red
Non-invasive, plug and play, 100 measurements per second, multifunctional, wireless data transfer, no moving parts
Bluetooth, RS485, CAN-Bus, UMB-protocol
