The VS2k visibility sensor measures visibility up to 2000m, ideal for road traffic applications on motorways, highways or bridges. A calibration device is 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 the standard protocol Lufft UMB. 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.
