Infrarotabsorption in CO2 (Treibhauseffekt)

IR-Quelle, einer Absorptionszelle mit Thermometer und einem IR-Detektor. Die Besonderheit in diesem Versuch liegt darin, dass sowohl Quelle als auch Detektor breitbandig sind. Man spricht daher auch von einem Integral-Absorptionsspektrometer. Die dargestellten Bauteile können auf einer optischen Bank gegeneinander verschoben werden. • Die Strahlungsquelle ist eine Wendel aus metallischem ...

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

If IR light is applied to a dual thermopile detector fitted with a pair of optical filters so that one filter is centered on 4260 nm and the other on 3910 nm, the concentration of carbon dioxide can be measured from the ratios of the two thermopile voltages. The optical filter that resides within the absorption channel serves as the detection channel and the optical filter that resides outside ...

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 ...
