For stationary operations we further developed the innovation award-winning mobile road weather Sensor MARWIS – this is StaRWIS!
StaRWIS is the first non-invasive road weather sensor detecting road and runway surface conditions, surface temperatures, relative humidity, dew point temperatures, ice percentages as well as friction non-invasively and based on innovative LED Technology with 4 lenses.
- Road condition (dry, moist, wet, ice, snow, slush, chemically wet), road surface temperature, water film height, dew point temperature, relative humidity, ice percentage, friction (calculated)
- Optical LED transmitters, photo receivers, pyrometer, infrared
- non-invasive, plug and play, 100 measurement per second, multifunctional, wireless data transfer, no moving parts
- Bluetooth, RS485, CAN-Bus, UMB – protocol
- 8711.U55
