INFRA-RED GAS ANALYZER Russian patent published in 1994 - IPC

FIELD: instrument engineering. SUBSTANCE: gas analyzer has a radiation source from which light beam is supplied to integrating space of a sphere where it interacts with the gas being analyzed. The radiation receiver readings will change depending on the concentration of the gas medium being analyzed. For multiple passage of radiation flux in the gas medium, the optical input and output are misaligned, and they do not pass through the center of the sphere. Infra-red light filter serves to form a part of the spectrum in which the radiation receiver possesses the highest sensitivity. EFFECT: enhanced gas analyzing process. 1 dwg
