Carbon Monoxide Sensor Based on Non-Dispersive Infrared ...

· Carbon monoxide (CO) is one of the toxic air pollution produced in incomplete combustion of carbon-containing fuels. At a certain threshold of concentration, this gas can harm the environments and affect the human health. Unfortunately, it cannot be detected by humans. In this study, CO gas detection has been designed and constructed using the principle of Non-Dispersive Infrared (NDIR). …

Operating principle ‐NDIR-type gas sensor

NDIR gas sensor consist of an infrared source, detector, optical filter, gas cell, and electronics for signal processing. A single light source, dual wavelength type gas sensor has two detectors and two optical filters of different wavelengths which are placed in front of each detector. Infrared light that is absorbed by a target gas passes through the active filter with a particular bandwidth ...

Continuous Emissions Monitoring Systems (CEMS) From A-Z: A ...

· NDIR analyzers incorporate a single beam photometric system and a detector with a micro flow sensor. A microflow detector is a sealed unit filled with the same gas as the component of interest (CO in this case). The length of the sample cell determines the most sensitive range for the CO component. The infrared gas analyzer measures gas concentration based on the principle that Carbon Monoxide ...
