Intelligent Active Road Sensor ARS31Pro-UMB

Description

Descripción

Description:

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 it measures 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. One additional measurement is carried out in order to find out critical conditions in the next few hours. This early alert message is an extra road surface condition information in addition to the road conditions which are measured „now“. The freezing temperature measurement is independent of mixture. The two-section housing design allows the combiend sensor/electronics unit to be removed for maintenance purposes at any time, in just a few minutes. In conjunction with the interface converter 8160.UISO, the sensor can be built into new and existing UMB networks. The sensors are addressable and can be networked.

Supplementary description:

The active freezing temperature sensor ARS31Pro-UMB from Lufft was proven successfully by the BASt following the valid inspection rules of CEN/TS 15518-4:2013.
