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 ...
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 ...
Sensor Installation Handbook Preface 3 rd edition Optimum control quality can only be achieved where accurate measure-ment is possible. This was the guiding principle behind the first edition of this sensor instal-lation handbook. The principle is still valid today, and questions of instru-mentation & control and sensor installation are more topical than ever. Legislation increasingly calls ...
