  • Basic Principle of NDIR Gas Detection - Heimann Sensor

    The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC). Also gases like carbon monoxide (CO) and nitrogen oxide (NO) are possible to detect. The most common applications for NDIR gas detection and gas analysis include, but not limited to: Air Quality Monitoring; Capnography

  • Nondispersive infrared sensor - Wikipedia

    A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

  • Measurement of NH3 Concentrations in Stack Flue Gas Using

    Process Overview. The NH 3 gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas, as well as to increase the dust collection efficiency of the dust collector (ESP) and prevent erosion. Excess NH 3 injection increases the running cost and the residual NH 3 amount, resulting in the generation of a foul odor. Therefore, the NH 3 concentration in the stack flue gas is measured, controlled, and monitored.

  • Refrigerant leak detection: IR vs SEMICONDUCTOR SENSORS

    When it comes to refrigerant leak detection, the predominant sensing technologies are undoubtedly Non-Dispersive InfraRed (NDIR) and Metal-Oxide Semiconductor (MOS), due to their ability to respond to this type of target gases and the many limitations of other common detecting methods such as electrochemical cells and catalytic pellistors.
