Vaisala’s Road Sensor DRS511 provides highly accurate and extremely reliable road-surface data. Cars can drive over the DRS511 without harming it, and because it’s placed directly where vehicle tires interact with the road’s surface, the passive sensor does not change or alter the environment where it resides, so the risk of failure or ineffectiveness is minimal. What’s more, it links to an RWS station that converts the data into a viewable format.
As you know, it takes several measurements to make confident road treatment decisions. Vaisala’s embedded DRS511 sensor not only provides the pavement temperature, but it goes one step further by simultaneously detecting the presence of moisture on the road surface to determine if the road state is dry, wet, icy, and/or covered with snow.

Vaisala’s Road Sensor DRS511 has been put to the test so you don’t have to be. The two PT100 elements in this passive sensor have been meticulously tested by authorities and institutions for years, helping road maintenance crews determine, with confidence, the chemical effectiveness in a wide range of weather conditions.
