1.Infrared methane sensor: technical principles and core advantages

    As a cutting-edge scientific and technological product in the field of gas detection, infrared gas sensors rely deeply on the specific absorption characteristics of different gas molecules in the near-infrared spectrum to accurately identify gas components and determine concentrations. Its working mechanism strictly follows the Lambert-Beer law-when a specific wavelength beam emitted by an infrared light source penetrates the gas environment to be measured, methane molecules will selectively absorb infrared light of the corresponding band, causing the light intensity to attenuate. In a pure environment without methane gas, the infrared beam can reach the detector with almost no loss; when methane gas enters the detection gas chamber, part of the infrared light is absorbed, resulting in a significant reduction in the light intensity that finally reaches the detector. By accurately calibrating and calibrating the infrared light absorption degree of the zero point and the standard measurement point, the real-time concentration of methane gas can be accurately calculated.

    This detection technology gives infrared methane sensors a series of excellent performance: its range can cover the full concentration range of 0-100%vol, which can meet the detection needs from trace leakage monitoring to extreme concentration environments; based on the specificity of spectral absorption, it has extremely high selectivity for methane gas and effectively avoids interference from other gases; it has anti-poisoning characteristics and can maintain stable operation under complex working conditions; it does not need to rely on oxygen to participate in the reaction, and completely gets rid of the detection limitations of traditional catalytic combustion sensors in oxygen-deficient environments; with a stable optical detection mechanism, it can achieve an ultra-long service life of up to several years and highly reliable long-term stability. These advantages enable it to directly replace traditional catalytic combustion components and be widely used in key areas such as general industrial sites, urban gas pipeline safety monitoring, and environmental protection department atmospheric pollution source monitoring, becoming a core component in conventional gas leak warning systems.

2. Intelligent infrared methane sensor product model: Take Tensensor as an example

    In industry application practice, the universal intelligent infrared methane sensor independently developed by Tensensor stands out with its advanced technology. Based on the principle of non-dispersive infrared (NDIR), this series of products can achieve high-precision and high-sensitivity detection of hydrocarbon combustible gases in the air. It is particularly suitable for high-risk and high-value industrial production scenarios such as petrochemicals, coal mining, and gas storage and transportation, and plays an irreplaceable key role in real-time online monitoring.
