product description
The embedded active road weather sensor ARS31-UMB 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 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 converter 8160.UISO, the sensor can be built into new and existing UMB networks. Passive sensor IRS31 and active sensor ARS31 can be combined without difficulty, in fact this is recommended. The sensors are addressable and hence can be networked.
- Two part housing design allows easy maintenance/re-calibration
- Low energy consumption allows solar operation
- Measuring range: from -40°C to 0°C
- Accuracy: ±0.5°C RMS for freezing temperature > -15 °C, or ±1.5°C RMS for freezing temperature < -15 °C (with NaCI)
