Electrochemical sensor of relative concentrations of reactive materials in a fluid mixture and system comprising such a sensor, especially for the regulation

摘要

the invention relates to an electrochemical sensor for relative concentrations in a fluid mixture, of the type employing a measuring cell consists of two electrodes (e1,.e2) placed on either side of a solid electrolyte (e1).according to the invention, the measuring cell, a planar electrode (e2), includes a catalytic material in at least one direction extended in parallel to the plane of the cell.a pre-determined length (ci).the fluid mixture is led to the analysis of thermodynamic equilibrium by placing in contact with the area (1) of the electrode (e2) or by diffusion within thethis prior to a second area (2) of the electrode (e2) or area measurement.;application to the control of combustion engines and burners of boilers.
