User Manual - ETCO2 Sensor - Cables and Sensors

The ETCO2 sensor uses an infrared absorption (IR) technique for monitoring CO2. The principle is based on the fact that CO2 molecules absorb infrared light energy at specific wavelengths, with the amount of energy absorbed being directly related to the CO2 concentration. When the IR light beam is passed through a gas sample containing CO2, an electronic signal from the photodetector can be ...

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.

Dräger Infrared Sensors - Draeger

The sensor set-up, selection of detectors and type of gas ingress are just a few of the factors that have a direct influence on the measuring performance of an IR sensor. Developing the sensors ourselves gives Dräger the opportunity to optimise these parameters, so they fulfil the requirements of various applications, personal monitoring, clearance measurements and leak detection.

Three-gas detection system with IR optical sensor based on ...

01/11/2015· With the fast development of IR sensors, a multi-channel IR gas sensor using Fabry–Perot Interferometer could be applied to detect the gases in the spectral range of 3–5 μm. Yet, it is feasible in the gas concentration from 0 to 500 ppm [9] , which may hardly be applied in some occasions, where higher concentration detection is needed, such as coal mine gas detection.

Go Direct® CO2 Gas Sensor User Manual – Vernier

The sensor uses a small light to generate infrared radiation (IR). The IR source is located at one end of the sensor’s shaft. At the other end of the shaft is an infrared sensor that measures how much radiation gets through the sample without being absorbed by the carbon dioxide molecules. The detector measures infrared radiation in the narrow band centered at 4260 nm. The greater the ...

FAQs - Gas Detectors | Gas Sensors by RKI Instruments

Many hydrocarbons absorb IR at approximately micrometers and in this region H2O and CO2 are relatively transparent. As mentioned earlier, there are some hydrocarbons and other flammable gases that have poor or no response on a general purpose IR sensor. In addition to aromatics and acetylene, hydrogen, ammonia and carbon monoxide also cannot be detected using IR technology with general ...

What is NDIR? | Oshino Lamps Ltd.

Incandescent lamps with tungsten filament are used for many NDIR CO2 sensors because enough infrared output can be obtained by that type of lamps. Those lamps also have wide wavelength length which covers from the visible light region to the near-infrared and mid-infrared regions. In particular, relatively large infrared output can be obtained at 3 µm to 5 µm wavelength which is required for ...

suited to these basic requirements. For NDIR it is usual to regard the sensor as an individual component in the instrument. The key feature is that fixed narrow-band filters are used with individual IR detectors to identify a few gas absorption lines over a limited wavelength range. (This cuts out the dispersive part of a gas spectrometer). Relatively inexpensive sensor components can be ...
