Ann Pattison of Lufft with the MARWIS sensor
Lufft is using the ITS World Congress to present the new, smart mobile road sensor Marwis (Mobile Advanced Road Weather Information Sensor) which will be available for delivery from next month.
The company says the sensor is the next big thing from its extensive line of innovative traffic technology solutions. Marwis can detect whether a road is dry, damp, wet, snowy or icy like a conventional road sensor.
It is also able to measure the surface temperature, the dew point, the air temperature, as well as ‘friction in motion’ with accurate ice film measurement. All of these capabilities are housed in a handy and portable ‘box’.
Marwis uses Bluetooth, Can-Bus and RS485 as interfaces and sends all recorded data to the cloud for display on a mobile device. Lufft says the sensor is limitless in its applications and is very cost-saving. For instance, it could reduce the use salt or help drivers know in real time how to take the safest routes.
With a proven protection class of IP68 Marwis will survive for hours submerged under more than one metre of water without damaging any of the inside electrical components and the device has passed an extreme vibration test and the test for electromagnetic compatibility with excellent results.
Other Lufft sensor solutions being shown during the event are the new IRS31Pro-UMB - the first invasive road sensor, which is able to measure friction, ARS31Pro-UMB and NIRS31-UMB – the first non-invasive road sensor, measuring with spectroscopy.
