A sensor with shallower physical dimensions to enable installation on
bridge decks.

|
Provides an accurate reading of surface conditions, including water, ice
and snow amounts and a high resolution value for grip level. Pole
mounted roadside set-up eliminates the disruption caused by
slot-cutting, making installation and maintenance relatively easy. Can
be used as a stand alone system on bridge decks, in remote locations or
as part of an existing ROSA weather station.

At the heart of the ROSA weather station, these cards provide the
interface between the road and atmospheric sensors and the data logger.

This thermally passive multi-variable sensor measures road / runway
surface and subsurface temperatures, as well as water layer thickness,
black ice and chemical levels.

Mobile road weather data collection began with only capturing air temperature and pavement temperature. The Vaisala Surface Patrol HD Pavement Temperature and Humidity Sensor WITH DISPLAY DSP211 adds atmospheric moisture. Monitoring dew point is very important in road weather because it can alert you to conditions favorable for the formation of frost or black ice on the road surface.

Fixed road weather stations are the perfect solution to monitoring road conditions; however, how do you monitor conditions in between stations? Adding weather sensors to vehicles is the solution. The Vaisala Surface Patrol Pavement Temperature Sensor is a perfect low cost, highly reliable sensor designed specifically for mobile use.

Winter maintenance operations use chemicals on the roadways to combat freezing of water or snow on the road surface. Knowing the condition of the pavement, especially the amount of chemical already applied, is an important measurement for making decisions about future chemical applications. The Vaisala SSI FP2000 is a passive, embedded pavement sensor that offers all road weather condition measurements in one sensor.
