Infrared Measurement Principle (NDIR) - ecom

NDIR analysers are particularly suitable for the determination of the concentration of carbon monoxide, carbon dioxide or hydrocarbons in a gas. Components of this process are a source of infrared radiation, an irradiated tube (cuvette) with the gas to be analysed, a wavelength filter and an infrared detector. The gas which has to be analysed is pumped into the sample. To ensure the sensor ...

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that ...

CO-Sensor | carbon monoxide concentration | smartGAS

CO sensors of the FLOW EVO series from smartGAS are ideal for this task: They operate on the basis of non-dispersive infrared (NDIR) absorption and therefore detect even minuscule carbon monoxide concentrations. The sensors are available for measuring ranges from 0 to 2000 ppm, 0 to 5000 ppm and 2, 10, 20, 50 and 100 Vol%.

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 for the detection of the target gas. Infrared light that does not interact with the target gas ...

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). …

Basic Principle of NDIR Gas Detection - Heimann Sensor

The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the Beer-Lambert law. 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 …
