The Active ARS31Pro-UMB Sensor is flush-mounted in the road/runway surface and measures the freezing temperature, by means of active cooling and heating, of the sensor surface. In addition, the ARS31Pro-UMB measures dry/wet conditions and the road surface temperature.
This surface temperature sensor is integrated into a second housing, which is connected with the ARS31Pro-UMB. The distance between the two housings is 50 cm.
