MEASURING PRINCIPLE IR MEASUREMENT Measuring Principle Depending on analyzer model different measuring methods will be used. 2.1 IR Measurement The measuring effect devided from absorption of infrared radiation is due to the gas being measured. The gas - specific wavelengths of the absorption bands characterize the type of gas while the strength of the absorption gives a measure of the concentration of the component measured.

PAGE 84
NGA 2000 MLT Hardware MEASURING PRINCIPLE IR MEASUREMENT Instruction Manual 90002929 07/2006 When the IR radiation passes through the measurement side of the analysis cell into the detector, a part of it is absorbed depending on gas concentration. Absorption chamber gas become colder, gas pressure in the absorption chamber is reduced and some gas of compensation chamber passes through the flow channel into the absorption chamber.
