• Lufft / OTT HydroMet VS2k-UMB 能见度传感器

      "Measures visibility up to 2000m, ideal for road traffic applications, analog output 4...20mA, digital UMB protocol (RS485 interface), calibration device available (optional). The VS2k-UMB is configured via the software UMB Config Tool: Reading\/Changing of the current configuration, calibration, polling of the current measurement values, the software allows configurations to be loaded and stored. The measurement data is available for further processing in the form of a standard protocol (Lufft UMB protocol or SDI12). ASD = Active Spider Defense: The built-in vibrating motor ensures at irregular intervals that the VS2k visibility sensor is not so prone to spiders. The construction of VS2k also reduces the frequency of maintenance."
