Surface Sensors


Bridge Surface Sensor

Bridge Surface Sensor

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


DSC111 Remote Surface Condition Sensor

DSC111 Remote Surface Condition Sensor

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.


DST111 Remote Surface Temperature Sensor

DST111 Remote Surface Temperature Sensor

Measures surface temperature via emitted infrared radiation. 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.


DRI521 and DRI511 Intelligent Road/Runway Sensor Interfaces

DRI521 and DRI511 Intelligent Road/Runway Sensor Interfaces

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


Vaisala Road / Runway Surface and Depth Sensor DRS511

Vaisala Road / Runway Surface and Depth Sensor DRS511

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


Vaisala Surface Patrol HD Pavement Temperature and Humidity Sensor Series DSP200

Vaisala Surface Patrol HD Pavement Temperature and Humidity Sensor Series DSP200

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.


Vaisala Surface Patrol Pavement Temperature Sensor Series DSP100

Vaisala Surface Patrol Pavement Temperature Sensor Series DSP100

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.


Vaisala SSI Passive Pavement Sensor FP2000

Vaisala SSI Passive Pavement Sensor FP2000

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.
