Page 12: Product Description
5 Product description 5.1 Design and function The meteorological network sensors are used for road weather monitoring. The device measures the surface temperature, ambient temperature and humidity, relative humidity at surface temperature, water film height and snow height on the road by means of non-invasive optical spectroscopy and a pyrometer. Thus the device can be used for the acquisition of a variety of measurement variables to determine the corresponding road conditions relevant for winter maintenance services. - Page 13 Color Description – Do not separate sensor from power supply! – Device error – The status channel device status provides detailed information about the type of error Blinking (any color) – Data transfer is currently taking place The status of the device and the measurement can also be retrieved via UMB channels 4000 and 4001. <13>...
