SF6 Gas Analysis: Ensuring Safety in Electrical Switchgear Operations
Electrical switchgear plays an indispensable role in the regulated distribution and management of electrical power in an array of environments, be it residential, commercial, or industrial. At the heart of these switchgear operations is the use of SF6 or sulphur hexafluoride, a highly potent greenhouse gas. Understanding the significance and roles of SF6 gas analysis becomes paramount in ...

SF6 Leak Detection with Edinburgh Sensors
SF6 leak detection is vital for SF6 gas concentration monitoring during production, handling and use. As an incredibly potent greenhouse gas, it is important that SF6 leaks are found early to prevent excess gas escaping into the atmosphere. What is SF6? SF6, or sulfur hexafluoride, is a colourless, odorless synthetic gas first synthesised in France in 1900 by Henri Moissan. SF6 was found to be ...

Controlling CO2 Emissions with Agricultural Gas Sensors
Agriculture in the UK is responsible for 9% of total greenhouse gas emissions, with that number rising to 30% of worldwide total emissions.1 There are a variety of sources for such gases in agriculture, including methane production from livestock, carbon dioxide release on soil disturbance, and emissions from farm machinery.2-4The question is how to reduce such emissions. Under the 2008 Climate ...

Gas Sensing Solutions for Agriculture Farming
Recently, there has been growing interest in how reducing our individual meat consumption could have a positive impact on greenhouse gas emissions.1 Each day, a single cow can produce as much as 250 – 500 L of methane gas.2 As well as the volume of methane produced being problematic, methane also has a greater warming effect than other greenhouse gases such as carbon dioxide due to methane ...

Ventilation Measurements Using Sulfur Hexafluoride (SF6) Tracer Gas
Sulfur Hexafluoride, also known as SF6, is by far the most common tracer gas used for ventilation studies. The primary reason is that it is easy to detect at very low concentrations—even in the parts per billion (ppb) or parts per trillion (ppt) range and has a very low toxicity. The best instrument to detect SF6 is an infrared spectrophotometer. Although the portable units are still a bit ...

Gas Detection and Monitoring Systems
In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

Methane emissions and airflow patterns along longwall faces and through bleeder ventilation systems
The National Institute for Occupational Safety and Health (NIOSH) conducted an investigation of longwall face and bleeder ventilation systems using tracer gas experiments and computer network ventilation. The condition of gateroad entries, along with the caved materials permeability and porosity changes as the longwall face advances, determine the resistance of the airflow pathways within the ...
