The embedded active road weather sensor ARS31 detects freezing temperatures independently from de-icing materials and is easy to maintain through its two parted housing.
The active road sensor ARS31 is installed flush with the road/runway surface and calculates the freezing temperature by means of active cooling and heating of the sensor surface. The freezing temperature measurement is independent of the mixture. The two-section housing design allows the combined sensor/electronics unit to be removed for maintenance purposes at any time, in just a few minutes. In conjunction with interface converter8160.UISO, the sensor can be built into new and existing UMB networks. Passive sensorIRS31 and active sensor ARS31 can be combined without difficulty, in fact, this is recommended. The sensors are addressable and hence can be networked.
