Methane (ch4 sensor) Gas Sensing Technology <br>NDIR <br>Non-dispersive infrared (NDIR) is an infrared source-based technology. NDIR methane gas sensor consist of an infrared source, detector, optical filter, gas cell, and electronics for signal processing. <br> <br>methane gas detector working principle is based on the property of certain gas molecules to absorb light at specific wavelengths. Infrared light that is absorbed by a target gas passes through the active filter with a particular bandwidth for the detection of the target gas. The absorption is calculated according to the Beer-Lambert law. The amount of absorption is proportional to the concentration of the target gas. <br> <br>Cubic NDIR technology adopts the matrix calibration assuring excellent accuracy over the full temperature range; dual-beam optical path design and smart compensation algorithm ensure reliable long-term stability, achieving credible safety monitoring. <br> <br>TDLAS <br>Tunable diode laser spectroscopy (TDLAS) is a narrowband laser-based technology. TDLAS methane sensor mainly consists of a laser light source, gas chamber and photodiode. <br> <br>The wavelength is tuned to the absorption optical spectrum of the target gas through periodic modulation of the input current. After targeted gas absorption, the remaining laser light will arrive at the photodiode which will be detected. The absorption is calculated according to the Beer-Lambert law. The amount of absorption relies on the optical path length in the gas chamber and the absorption coefficient of the target gas. <br> <br>Cubic TDLAS technology adopts a long laser light path by multiple reflections, enabling low range, superior-low detection limit, and high-resolution quantitative measurement. <br> <br>Why Cubic Methane Detection Solutions? <br>Mature Optical Technology PlatformScaled and Sustainable ManufacturingVertical Supply Chain IntegrationHigh Quality Control and Assurance <br>Mature Optical Technology Platform <br>More than 20 years of commitment to optical gas sensing technology for methane emission monitoring solutions. <br> <br>Scaled and Sustainable Manufacturing <br>Scaled and sustainable manufacturing capabilities to ensure reliable deliveries. <br> <br>Vertical Supply Chain Integration <br>By implementing large-scale production and melding self-developed components for integration to realize meticulous cost innovation. <br> <br>High Quality Control and Assurance <br>Complete laboratory testing capabilities and strict quality control systems to ensure high-quality products from R&amp;D to applications. <br> <br>For more information about methane sensor technology and methane sensor ppm, please feel free to contact us! <br> <br>Cubic sensor is a leading manufacturer of gas sensors and gas analyzers.
