  • Area Monitoring: Diffusion Sampling

    Indoor and outdoor gas hazards that exist in open areas are usually monitored using diffusion-type sensors. A diffusion sensor has no active sample-drawing system; diffusion sensors rely on the ambient air movement and pressure to deliver the sample to the sensing element. Diffusion-type sensors are a reliable and cost-effective way to monitor open area gas hazards. When installing diffusion ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...


  • CO2 Gas Hazards in the Brewing Industry

    The hazards associated with CO2 in the brewing industry are well known, yet people still die needlessly every year in tragic and completely avoidable accidents in breweries. Just last year in Germany, which has a good safety record, two workers died in separate incidents at the same brewery. In the first incident, the owner was found dead with his head and torso in a beer mixing tank. It is ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

  • Paint booths, or areas using combustible gases: why a requirement for combustible gas monitor might be necessary

    Paint booths save time and ensure a smooth and professional application of paint in a range of industries, including automotive, aerospace, home decor, furniture, and more. Combustible gases and fluids in the paint booth environment can pose a health hazard if something goes wrong. Explore the hidden dangers of paint booth fluids and gases, and learn how a ...

  • 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 ...

  • Fixed multi-parameter gas detection system can ensure industrial facilities are safe from hazardous or toxic gases

    Industrial workplaces are likely to come across one or more hazardous or toxic gases. Combustible gases such as methane are highly dangerous because they can cause large and fatal explosions when ignited. Other problem areas when working in industry are carbon monoxide (which poisons the cardiovascular system), oxygen deficiency, and elevated levels of other gases and pollutants, depending and ...

  • Comparative investigation of Source Term Estimation algorithms using FUSION field trial 2007 data: linear regression analysis

    Given a warning based on detections at a few sensors, it should be useful to rapidly provide an estimate of the location, time of release and amount of material released. Such information could lead to refined predictions of the hazardous area and support follow–on actions to investigate the cause and nature of the hazardous release. In September 2007, a short–range test designed to ...

  • 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 ...

  • Developing Technologies to Detect Hydrogen Sulfide (H2S) Gas

    Abstract Hydrogen sulfi de (H2S) gas can cause nausea, headaches, unconsciousness, and death. Industries struggle to detect this deadly substance before it harms workers or communities. Safety system manufacturers have developed detectors that sense the H2S quickly and accurately. This paper illustrates, in general terms, considerations in effective placement of H2S detectors: ...

  • Monitoring DMA level case study

    ABIC, a leading provider of veterinary products chooses MonoScan to monitor the level of DMA (Dimethylamine) tank in one of its plants located in Israel.

  • Detecting Gases: What You Can`t Smell Can Hurt You

    Walking through a drill-site area, a worker smells rotten eggs and stops tor a minute or two to assess where a gas leak might exist. Rubbing his itchv eves as he investigates further, he notices that he no longer smells the tell¬tale hydrogen sulphide odour. He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose ...

  • Selecting and Placing Gas Detectors for Maximum Application Protection
