Alternative product D-R 290 (2. G)

The D-R 290 works according to the transmission principle. The measurement is continuous, non-contact and without sampling in the exhaust gas flow. The D-R 290 is particularly suitable for monitoring medium to high dust concentrations.

For tunnel projects SMART/AQM

Air quality monitor with IoT visible opacity and gas sensor for use in tunnels. Visibility measurement is based on the scattered light principle, gas measurement with up to 3 electrochemical cells.

New version of the known Lufft VS20 visibility sensor with a measurement range of 10-20,000m, easy calibration functionality, sea waterproof housing and (active) spider defence.

The VS20k visibility sensor measures visibility up to 20,000 m, ideal for road traffic applications on motorways, highways or bridges.

A calibration device is available (optional).

The VS20k-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.

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.

The OWI-430 DSP-WIVIS is a fully automated weather and visibility sensor that provides accurate visibility, present weather and precipitation measurement in a single sensor.

This 3rd generation intelligent sensor uses all digital signal processing (DSP) for no-drift high-accuracy results. OSi’s patented environmentally adaptive algorithms use artificial-intelligence technology derived from over 200 million field hours of real-world data from our sensors installed around the world. 

The DSP-WIVIS measures visibility and detects and quantifies rain, snow, drizzle, freezing and mixed precipitation conditions. The -DSH model identifies whether visibility impairments are caused by haze/fog vs. dust/smoke. The sensor is designed for year-round continuous operation in all climates from Antarctica to tropical rain forests. OSI’s advanced weather sensors provide critical weather information to airport, highway, military, research and meteorological weather information systems all over the world with over 3000 systems fielded.

Thanks to the new DSP electronics, the need for field calibration is eliminated. The single enclosure makes integration and installation simple. Adding the optional HIP-100 acoustic sensor provides for enhanced hail and ice pellet discrimination. The DSP-WIVIS is widely used by airports and regional DOT’s across the US and throughout the world.
