Carbon Dioxide Sensor - Sensor Technology | Sensors ...

The IR sensor measures the amount of radiation that passes through the sample without being absorbed by the carbon dioxide molecules. The sensor measures the IR radiation absorbed in the narrow band at 4260 nm. The greater the absorbing gas concentration in the sampling tube, the lesser the amount of radiation from the source. As a result of this increase in temperature, a voltage is generated ...

What is an NDIR Sensor? - Sensor Technology | Sensors ...

05/12/2018· Similar to every IR gas sensor, the analyzer used at Mauna Loa used the same basic principle for measuring CO2. It involves an infrared light radiation source at one end of a gas sample tube and an IR detector at the other end. The absorption band of CO2 is , alike to the micron band of infrared radiation. Consequently, the quantity of light radiation that is absorbed by the CO2 ...

Thermal Conductivity versus Infrared CO2 Sensors | Blog ...

06/10/2018· The CO2Cell Incubator and the SCO Air Jacket CO2 Incubator both utilize IR sensors. The sensor can detect how much CO 2 is in the atmosphere by measuring how much μm light passes through it. The big difference here is that the amount of light detected is not dependent on any other factors, such as temperature and humidity, as is the case with thermal resistance. This means you …
