GAS sensor using a band pass filter for temperature measurement SOURCE

摘要

FIELD: physics.;SUBSTANCE: sensor having a filter device, at the output of which there is a detector device, and an analysis device which is connected to the detector device. The filter device has a first control filter and a second control filter, the two filters having a first control band and a second control band respectively. The measured intensity densities of the first control band and the second control band are used to estimate the temperature of the radiating source. The first and second control filters form a control system, and control bands thereof form a system of control bands distributed on both sides of a preliminary band.;EFFECT: high measurement accuracy.;9 cl, 13 dwg
