Reparo do sensor de CO2 IR

Carbon Dioxide Sensor Sensor Technology | Sensors ...

The carbon dioxide gas sensor measures gaseous carbon dioxide levels by detecting the quantity of IR radiation absorbed by carbon dioxide molecules. The sensor employs a hot metal filament that acts as an IR source to generate IR radiation. The IR source is located at one end of a sensor tube, and another end is provided with an IR sensor.

Sobre emissão de poluentes veicular? – Pergunte Aqui!

Dec 18, 2010· Outro gás importante na análise de emissões é o NOx (Óxidos de nitrogênio), porém, este gás é disperso em situações de carga do motor e em temperaturas superiores a 1300ºC a 1400ºC na câmara de combustão, portanto, para simulação em laboratório, é necessária a utilização de um dinamômetro. Além do reparo, a análise de ...

CO2 Sensors vs. VOC Sensors for IAQ What''s the ...

CO2 sensing technology by IR (infrared) is stable and is not subject to the shortterm, random drift found in air quality sensors. Most IR carbon dioxide sensors only measure CO2. A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air.
