NON-DISPERSING MULTI-PASSAGE INFRA-RED GAS ANALYZER Russian patent published in 2002 - IPC

FIELD: measurement technology; devices for determination of concentration of components of multi-component gases. SUBSTANCE: infra-red radiation of proposed non-dispersing multi-passage gas analyzer is created by conversion of infra-red radiation from light-emitting diode by means of photoluminescent transducers and application of interference filters on light-emitting matrix; photo detector used directly in radiation source records intensity of radiation λ₀ of pumping light-emitting diode; effect of change of intensity of pumping of photoluminescent structure. EFFECT: enhanced accuracy of determination of concentration of components of multi-component gas due to enhanced stability of source parameters. 2 cl, 3 dwg
