DST111 Road Surface Temperature Sensor
We measure the amount of infrared radiation emitted from the road surface, perform signal processing, and accurately measure the surface temperature.
The DST111 sensor can measure road surface temperature non-contactly. It measures the amount of infrared radiation emitted from the road surface, processes the signal, and accurately measures the road surface temperature. Even under environmental conditions where many commercially available infrared sensors show errors, reliable measurement values can be obtained. When the road surface temperature drops due to radiative cooling on clear nights, typical infrared sensors can experience errors of up to -3°C due to the influence of the road surface's emissivity, but the DST111 corrects this error through its unique design to display accurate data. The installation method for the DST111 is simple, requiring no cutting of the road surface or road closures. By using mobile communication devices, it is an ideal standalone sensor that can be used in remote locations or on bridges. This sensor is designed to be installed directly on existing structures such as columns along the roadside. It can also be combined with existing Vaisala Road Weather Stations RWS200 or older ROSA Road Weather Monitoring Stations. When combined with the DSC111 road surface sensor, it forms a versatile standalone weather station.
