Vaisala DST111 Remote Road Surface Temperature Sensor
The unique DST111 sensor provides a remote alternative to measuring road surface temperature. By measuring the infrared radiation emitted by the surface and applying intelligent signal processing, DST111 provides a reliable remote surface temperature measurement.
DST111 provides reliable results in conditions where most of the commercially available infrared sensors fail. At night time, when the road surface is cooling under a clear sky, conventional infrared sensors provide an error of up to -3°C due to emissivity conditions of the road surface. DST111 compensates for this error by its unique design.
Installation of DST11 is easy, requiring no slot cutting or closure of the road. Supplied with solar/gsm options, the sensor is ideal for stand-alone operation in remote/in-fill locations and on bridge decks. The sensor is simply installed on a mast, or existing structure beside the road.
DST111 can also be installed alongside an existing Vaisala ROSA Road Weather Station. Together with DSC111, which measures surface state, DST111 forms a versatile stand-alone weather station.
