Methane is colourless, odourless gas that is is extremely volatile and a major fire risk.
Methane monitoring is a critical health and safety issue for industries where it is a byproduct.
Non-dispersive infrared (NDIR) is an effective method for measuring methane since it does not rely on the presence of oxygen.
Edinburgh Sensors* is specialises in Infrared (IR) Gas Sensors.
Methane monitoring can be achieved with infrared gas sensors because the gas absorbs IR light at a specific wavelength.
Within the detector, an IR light source is placed at one end and an absorbance detector at the other end, with an optical filter that will exclude all wavelengths except from where methane absorbs IR light. As air fills the chamber, methane particles begin to absorb the IR radiation. As methane concentration increases and more light is absorbed, the IR light signal at the detector decreases, setting off the sensor.
*Edinburg Sensors origin from UK have designed and manufactured a comprehensive range of gas sensor based on non-dispersive Infared (NDIR), fail safe gas sensing technology since 1980.
