  • NDIR Sensor for Non-Dispersive Infrared Detection

    IR Gas SensorsNon-Dispersive Infrared (NDIR) SensorsEliminating ErrorsAre You Looking For An Ndir Sensor?Commercial IR gas sensors generally consist of an infrared source, a detector, a gas cell/path, a wavelength selection device and some optical components (lenses or more usually mirrors) to couple the radiation from the source through the gas cell to the detector. The sample gas passes through the gas cell and the detector measures the radiation at the absorption band wavelength of the target gas. When no target gas is present there is no absorbance so the signal reaching the detector is at a maximum. When the target gas is present in the path, the detected signal reduces as the target gas concentration increases.

  • Using an Infrared Sensor for Reliable Methane - Gas Detection

    Gas Detectors Are Widely Used to Detect Leaks and Monitor Methane ConcentrationsCommercially Available Gas Detection TechnologiesInfrared Sensor (IR Sensor) Is The Technology of Choice For Methane DetectionEdinburgh Sensors Gascard Ng For Reliable Gas DetectionReferences and Further ReadingNatural gas, which mainly consists of methane, is widely used in power generation. However, methane is a greenhouse gas, extremely flammable, and can form explosive mixtures in air. Methane leaks can have devastating results, so detecting leaks is vital during natural gas extraction, transportation, and power generation.2-4 In the chemical industry production of syngas, methanol, acetic acid and other commodity chemicals depend on methane gas sensors to ensure that processes are operating safely and efficiently. Measuring atmospheric levels of methane is also becoming increasingly important for monitoring changing environmental conditions that may affect the environment and human health.2-4
