  • Determination of the relative and absolute humidity in Compost piles by differential pectroscopy using Tuneable diode lasers

    The composting of biological waste is an important step towards the establishment of closed cycles of matter. A constantly high quality of the compost is, however, of utmost importance for the deliberate re-introduction of compost into the environment. The quality of the compost produced is determined by a very complex biological process during which the organic wastes are converted with the aid ...

  • Performance characteristics of a Thin-film aluminum oxide humidity sensor - Case Study

    Summary A laboratory study was made of the performance of a miniature-size, thin-film aluminum oxide humidily sensor over a range of ambient temperatures from 0°C to 40°C and encompassing humidities from 40 to 78,000 parts per million by volume (ppm-v). Hysteresis and temperature effects of the sensors were obtained from tests performed at ambient temperatures 40°C, 25°C and ...

  • Case study - Buoy-based temperature profiling in the Bavarian Lakes

    In summertime a temperature stratification occurs in deep lakes – the surface water is warm, but deep down the water is cold.  This has considerable influence on the nutrient balance and the biological habitat in these lakes. Due to generally higher air temperatures induced by the climate change, both change and have effects on the life conditions of the ecosystems in the lakes. ...

  • Nanostructured oxyspinel multilayers for novel high-efficient conversion and control

    Multilayered temperature-/humidity-sensitive thick-film p - i - p + structures based on spinel-type semiconducting ceramics of different chemical composition (Cu 0.1 Ni 0.1 Co 1.6 Mn 1.2 O 4 with p + -type of electrical conductivity and Cu 0.1 Ni 0.8 Co ...

  • ´More Stations. More Data. Better Forecasts.´ – the NYS Mesonet

    “More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • 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 ...

  • Great Lakes need great Data Buoys

    One recently finished project was performed by the University of Wisconsin and has comprised the depolyment of two data buoys which are both furnished with a multifunctional Lufft WS501-UMB. These weather ...

  • Advanced offshore measurements to support wind energy production, weather forecasting, and emergency response

    Sonoma Technology, Inc. (STI), with support from the Bureau of Ocean Energy Management, is leading a unique partnership of corporate, government, and university researchers to develop a marine environmental observations program in the Gulf of Mexico. The primary goal of this project is to develop a framework of advanced offshore measurements to support emergency response, oil and gas exploration ...

  • Future inside – smart environmental sensing technology

    SHM30 snow depth sensor in Antarctica (photo: Alfred-Wegener-Institut, Helmholtz-Zentrum Bremerhaven) A lot of sensing technologies have changed recently: Ultrasonic wind measurement replaces cups and vane systems, closed anemometer designs offer better protection from ...

  • Projected leaf area and flow rate - options and observed effects on gas exchange measurements with CIRAS-2

    From a practical and theoretical standpoint, the objective in using gas exchange technology is to capture representative plant/soil physiological data, holding instrument error to a minimum. A basic goal in this is to ensure that sampling reflects real responses to natural or imposed environmental variability (treatments). Whether from an observational or experimental approach, the physiological ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...

  • 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 ...

  • Moisture in Oils: The Three-Headed Beast

    Abstract Moisture contamination in in-service lube oils is perhaps one of the most destructive forms of engine corrosion second only to particle contamination.  Water contamination in oil can be categorized into three forms of water; Free, emulsified, and dissolved.  All forms of water have direct consequences to the oil and gears of the engine, but indirect consequences as ...
