StaRWIS-UMB - Stationary Road Weather Information Sensor
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 & freezing 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, freezing temperature, 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
Advantages of the stationary non-invasive road sensor StaRWIS
- No moving parts due to award-winning and innovative LED Technology
- Non-invasive measurement principle
- Data transfer via Bluetooth, RS485 or CAN-Bus
- Mulifunctionality
- Measurements both on the ground and in the ambient air
- Easy to install and to clean
Examples of use of the stationary non-invasive road sensor StaRWIS
- Decision support for winter maintenance operators on roads, motorways, highways (municipalities, federal states and provinces)
- Decision support for the de-icing of runways (higher efficiency)
- As important part of the IDS (Ice Detection System) in form of a RCC (Runway Condition Code), water film height (aqua-planning risk) and friction detector on airports (digital alternative to mechanic grip testers)
- For smart city applications
- For weather data collection and weather forecast model improvements
