  • How clean is your local air?

    Few people know how clean the air is where they live, work, exercise or where their children go to school. Although air quality can be shown to vary significantly over short distances, air pollution is generally measured using a small number of large, expensive and high quality monitoring stations. The equipment used in these stations is very accurate and complies with measurement standards but ...

  • The New Generation of the UMB Config Tool: Discover ConfigTool .NET

    It is hard to imagine that until recently I had nothing to do with apps and graphical programming, but I had been satisfied with my bits and bytes. They are the innermost of every computer. When I was programming the new ConfigTool with Windows and Android programming, I quickly took pleasure on it and teached it myself. This is partly due ...

  • Monitoring Air Makes Sense

    Did you know that air filters were originally put in air handling systems to protect the life of the equipment, not human life? And that it is not uncommon for air filters to get changed less frequently to save on maintenance costs? Monitoring input from sensors can tell operators when filters and media need changing. We have required food labels that list all ingredients. Why not electronic ...

  • 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 ...

  • Application of nanocrystalline metal oxide gas sensors for air quality monitoring

    Increasing concern regarding health effects caused by air pollution, together with the limited spatial resolution achievable with conventional monitoring stations, have driven efforts to develop inexpensive metal oxide gas sensors for air quality measurements. The sensing mechanism is dependent on physicochemical reactions between adsorbed gas molecules and oxygen species on the oxide surface, ...

  • Multiple sensor fault detection and isolation of an air quality monitoring network using RBF-NLPCA model

    This paper presents a data-driven method based on non-linear principal component analysis to detect and isolate multiple sensor faults. The RBF-NLPCA model is obtained by combining a principal curve algorithm and two three-layer radial basis function (RBF) networks. The reconstruction approach for multiple sensors is proposed in the non-linear case and successfully applied for multiple sensor ...

  • Instrument air case study

    Application Moisture is measured in instrument air to ensure that the air is properly dried. Problem Instrument air is used through-out a facility to protect delicate electronics, instruments, and to operate key process actuators. Many instruments also use instrument air to operate various pneumatic operators they might possess. Too frequently, there is ...

  • Monitoring in the near future

    Take a look into the lab to see how commercialization of advanced environmental sensory capability is about to happen. Being asked to describe technology breakthroughs in environmental sensors with applications like air and water monitoring prompts the obvious question, 'If the first micro-machined gas chromatograph was demonstrated in 1979, why didn't the environmental sensor market experience ...

  • MONITORING & ALERT NETWORK in response to the health problems of Sargasso algae

    Martinique has been facing a major health problem in recent years. Indeed, since 2011, the unprecedented phenomenon of massive stranding of Sargasso algae has affected the Atlantic and southern coasts of Martinique. This phenomenon is the origin of a smelling gas emanating from the putrefaction of algae, among these gases hydrogen sulfide (H2S) and ammonia (NH3). Beyond the olfactory discomfort, ...
