OPTICAL MULTISENSOR BASED ON W AND NI OXIDE FILMS FOR THE DETERMINATION OF CO AND H2 CONCENTRATION
Journal Title: Сенсорна електроніка і мікросистемні технології - Year 2014, Vol 11, Issue 3
Abstract
An optical sensor for the determination of H2 and CO concentration in a mixture with air has been developed. The sensor has an explosion-proof design, which is achieved by the use of an optical measurement scheme. Tests of this sensor during the simuetaneous determination of H2 and CO concentration showed a high sensitivity and selectivity of optical elements based on gasochromic WO3 /Pd and NiOOH films. It has been shows that the main change in light transmission range 0,1-4 vol. % H2 or CO in air
