OPTICAL-ABSORPTION SYSTEM FOR GAS ANALYSIS WITH COMPENSATION OF DESTABILIZATION FACTORS

摘要

An optical-absorption system for gas analysis with compensation of destabilization factors comprises a source of infrared radiation, working cell and comparative one, obturator output of which is connected to the input of interferential light filter, output of that one is connected to the input of concentrator, output of this one is connected to the input of the photo-receiver output of which is connected to the input of the main amplifier output of which is connected to the first input of the synchronous detector. The second input of that one is connected to the output of photo-detector, the output of the synchronous detector is connected to the first input of the device for information processing, output of this one is connected to the input of the display. Measuring temperature and gas humidity sensors are included, the outputs of those are connected, respectively, to the second and the third input of the device for information processing.
