Operating principle of infrared measurement
This measuring principle is based on the molecule-specific absorption of bands of infrared
radiation, which in turn is based on the "single-beam procedure".
A radiation source (7) operating at 600 °C (1111 °F) emits infrared radiation, which is then
modulated by a chopper (5) at 8 1/3 Hz.
The infrared radiation passes through the analyzer chamber (4), into which sample gas is
flowing, and its intensity is weakened as a function of the concentration of the measured
component.
The receiver chamber (detector) - set up as a two- or three-layer detector - is filled with the
component to be measured. The first detector layer (11) primarily absorbs energy from the
central sections of the sample gas IR bands. Energy from the peripheral sections of the
bands is absorbed by the second (2) and third (12) detector layers. The microflow sensor
