  • 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 ...


  • 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 ...

  • A New Method for Inter-Coil Short Circuit Detection in Synchronous Machine Armature Winding

    Abstract Detection of inter-coil short circuits has a significant importance in nowadays diagnostics of rotating electrical machines. In this paper two modern, reliable and economically viable methods for such detection in excitation windings of turbo generator have been described. One can be applied in operation and the other in standstill condition. First method for ...

  • Remote sensing of land degradation: experiences from Latin America and the Caribbean

    Received for publication April 6, 2009. Land degradation caused by deforestation, overgrazing, and inappropriate irrigation practices affects about 16% of Latin America and the Caribbean (LAC). This paper addresses issues related to the application of remote sensing technologies for the identification and mapping of land degradation features, with special attention to the LAC region. The ...

  • Comparison of Directional WaveGuide Radar with Directional WaveRider Buoy

    Abstract Down looking FMCW radars for measuring water level, tides and wave height have been in use for 25 years. A combination of three down looking FMCW radars, mounted on an o↵ shore location, can be used to accurately measure ocean wave height and wave direction. At locations where an o↵shore mounting construction is readily available, the major advantage of this relatively ...

  • Black Box for Electrical Machines

    Abstract This article describes a specific monitoring system for electrical machines, called black box for electrical machines (Electrical Machines Black Box, EMBB).  Detailed analysis about problems of harmful working conditions that can occur on all electrical machines has been made. Based on these data and on measurement and control ...

  • Danger and Detection of Hydrogen Sulphide Gas in Oil and Gas Exploration and Production

    A rig worker smells rotten eggs near the well head, rubs his itchy eyes as he investigates the frosty pipe connections. After a few moments, he believes all is fine as he no longer smells the tell-tale hydrogen sulphide odour. In this scenario, we can only hope the worker recognises the danger and quickly leaves the site. Oil fields, especially mature ones, can produce hydrogen sulphide gas ...

  • Water Quality Monitoring and Testing Using an Environmental Logger

    Intelligent dataTaker System from CAS DataLoggers Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental management. Turbidity, conductivity, ...

  • Former Ordnance Survey – Case Study

    Project Highlights Envirochem carried out environmental perimeter monitoring during the demolition of the former Ordnance survey site in Southampton. Airborne Dust, noise and vibration levels were all monitored using state of the art equipment. Project Description ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • U.S. headed for massive decline in carbon emissions*

    For years now, many members of Congress have insisted that cutting carbon emissions was difficult, if not impossible. It is not. During the two years since 2007, carbon emissions have dropped 9 percent. While part of this drop is from the recession, part of it is also from efficiency gains and from replacing coal with natural gas, wind, solar, and geothermal energy. The United States has ended a ...

  • Torque about improving handling accuracy

    Dry bulk handling is en route to becoming a precision science with a level of control previously undreamt of, thanks to 20 years of research and development into digital non-contact torque monitoring. Dry bulk handling is following many other industrial processes that have been redeveloped from a ‘black art’ to a highly accurate and controlled procedure. A generation ago much of industry was in ...

  • Waterquality and meteorological data - Greece

    Background Thesprotia is one of the 51 prefectures in Greece and is located in the North-West of the country, 479 km from the capital Athens. The population of the prefecture is around 46,000 people. In the Pindos-Mountains arises the riverKalamas and empties after 115 km in the bay of Valtos (Ionian Sea). The river has large environmental influence on the area and is also in some areas ...

  • Could food shortages bring down civilization?

    “In early 2008, Saudi Arabia announced that, after being self-sufficient in wheat for over 20 years, the non-replenishable aquifer it had been pumping for irrigation was largely depleted,” writes Lester R. Brown in his new book, Plan B 4.0: Mobilizing to Save Civilization (W.W. Norton & Company). “In response, officials said they would reduce their wheat harvest by one eighth each year ...

  • Monitoring mixing dynamics in Toolik Lake, Alaska

    Toolik Lake is 130 miles south of Prudhoe Bay in northern Alaska. It is one of the main monitoring sites of the Arctic Long-Term Ecological Research (LTER) project and a site for studies led by Sally MacIntyre of the University of California investigating the linkages between hydrodynamics and ecosystem function. Both studies are funded by the U.S. National Science Foundation. It is classified as ...

  • Europe should embrace `clean revolution`

    Companies have to courageously embrace the clean revolution but political leaders have to be ambitious enough to allow the economic certainty to invest in the technologies of tomorrow in all of the EU member states, writes Steve Howard, chief sustainability officer at IKEA, in an exclusive op-ed for EurActiv. Steve Howard is chief sustainability officer at IKEA, one of the 70 companies calling ...
