RCM411 is an optical sensor based on spectral analysis. The firmware of the sensor measures the optical reflection signals and analyses the data to produce a road surface condition and friction report.

RCM411 reports the following road surface information

• Surface     condition

• Coefficient     of friction

• Water layer thickness

RCM411 sensor highlights

• Easy and fast     installation in any vehicle, from passenger vehicles to plough trucks,     easily transferable to another vehicle

• Low     purchasing cost and economic life cycle costs of the total measurement     system

• The system is     almost maintenance free: only cleaning of lenses may occasionally be     needed

• Automatic software updates and remote control of     parameters
