Professional Mobile Weather Data Recording
Sensors are mounted on vehicles in accordance with the requirements for a road traf c meteorological monitoring network. MARWIS for the detection of water, ice and snow as well as friction can be installed on vehicles with a distance of 1 or 2 meters between the measuring instrument and the object of measurement.
MARWIS delivers the following data:
- Road conditions: dry, moist, wet, snow, ice
- Road surface temperature
- Waterfi lm height
- Dew point temperature
- Ice percentage
- Friction
- Rel. humidity above road surface
When the number of ice particles on the road surface increases, the friction coef cient falls and can thus serve as an important element of decision-making with regard to preventive gritting. Due to the open interface (RS485, Bluetooth, CAN), MARWIS can be easily integrated into existing winter maintenance monitoring networks. Similarly, MARWIS can communicate directly with the control system on gritting vehicles.
