AMPEROMETRIC SENSOR FOR MEASURING CONCENTRATION OF METHANE AND HYDROGEN IMPURITIES IN ANALYSED GAS MIXTURE

摘要

FIELD: physics.;SUBSTANCE: invention relates to analytical equipment and can be used for measurement of content in gas mixtures of limit hydrocarbons, such as methane and ethane, as well as content of hydrogen admixtures in them. Amperometric sensor for measuring concentration of methane and hydrogen impurities in the analysed gas mixture comprises disks from an oxygen-conducting solid electrolyte with electrodes, wherein the sensor comprises a disk from an oxygen-conducting electrolyte, on opposite surfaces of which there is a pair of electrodes, disk from proton-conducting solid electrolyte, on opposite surfaces of which there is a pair of electrodes, and between these disks there is an electrodeless disk made of oxygen-conducting solid electrolyte tightly connected to electrode disks to form two cavities with capillaries.;EFFECT: technical result is possibility of simultaneous measurement of gas content of methane and hydrogen admixtures in gas mixture.;1 cl, 5 dwg
