  • What are the advantages of ultrasonic wind sensors?

    Whether mechanical, ultrasonic or laser wind measurements: All measuring methods have technical limits. While for mechanical wind sensors the measuring element – cups and vanes – itself predominantly produces a disturbance in the flow field, for ultrasonic anemometers a disturbance can be caused by the sensor holder or housing construction. Only optical methods, e.g. LDA (Laser ...

  • Does Ultrasonic Wind Sensor VENTUS-UMB pass extreme tests?

    Sometimes we give our sensors a hard time. But this has a good cause: We want to guarantee the high quality and the keeping of our promises. A few weeks ago, the ultrasonic wind sensor VENTUS was the one to be challenged. We exposed the modern measurement device to extreme conditions. But did it endure these conditions? And where occurs enough wind to challenge the strong sensor at all? Wind ...

  • Wind turbine controlling of the future

    Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

  • New methods for measuring the wind

    Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...


  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • Sensors and Sensitivity - The need for smart environmental sensing technology

    With the rapid increase in technology, environmental sensors are required to perform for a multitude of systems and must also comply with the Internet of Things. Over the past 100 years, environmental sensors have mainly been used to forecast the weather. Over the past 10 years, these sensing technologies have spread tremendously and now help to optimize many industrial processes; important ...

  • Safe Landings Whatever the Weather: Lufft Sensors on Airports

    Pilots, air traffic controllers and airport operators do their best to make air travel safer and more efficient. Sometimes, however, flight security depends on external factors we can hardly influence. This especially refers to risky weather conditions: Strong winds, icy cold or strong precipitation can have serious consequences. On average, 23% of all aircraft accidents and 68% of canceled ...

  • On the wind flow patterns under neutral and unstable conditions in an urban area

    Wind flow and pollutant dispersion within urban areas depend on the approaching flow profile and temperature stratification. Thus, the flow field developed under neutral and unstable stratification conditions, within a street–canyon, was studied experimentally and numerically for a two–dimensional urban background set–up. Wind–tunnel measurements were carried out with a triple hot sensor ...

  • Radar remote sensing of wind-driven land degradation processes in northeastern Patagonia

    Received for publication February 27, 2009. Wind-driven land degradation negatively impacts on rangeland production and infrastructure in the Valdes Peninsula, northeastern Patagonia. The Valdes Peninsula has the most noticeable dunefields of the Patagonian drylands. Wind erosion has been assessed at different scales in this region, but often with limited data. In general, terrain features caused ...

  • Finite element analysis of turbine generator rotor winding shorted turns

    Abstract Online magnetic flux monitoring via permanently installed air-gap flux probes is a well- established technology to determine the presence of shorted turns in a turbine generator rotor winding. Flux measurements are normally performed using flux probes installed in the machine air gap (on a stator wedge) and connected to portable or permanently installed instruments. In this ...

  • TSI dust monitors and Lufft weather sensors make a great team

    Both aerosols and wind speed and direction influence air quality significantly. This is why TSI Incorporated, a world leader in particle measurements, cooperates with Lufft USA in order to provide complete systems to measure PM2.5 (fine dust), PM10 (particles with a maximum diameter of 10 μm) as well as total PM levels. TSI Incorporated offers a variety of aerosol ...

  • Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

    Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...

  • Method for comparison of large eddy simulation generated wind fluctuations with short–range observations

    The often prohibitive costs of comprehensive field trials coupled with relatively cheap and abundant computational power leads to a strong desire to use modelling tools to supplement field testing of system components. These modelling tools must be capable of reproducing key environmental variables present during field testing and require rigorous validation. The Virtual THreat Response Emulation ...
