PROCEDURE FOR CALIBRATION OF TRANSDUCER OF VOLUME CONCENTRATION Russian patent published in 2003 - IPC

FIELD: determination of concentration of various binary gas mixtures, heat power, chemical, aircraft and other branches of industry. SUBSTANCE: procedure includes preparation of binary gas mixture of certain concentration in vessel and measurement of concentration with the aid of transducer. Gas and air mixture is prepared by way of evacuation of air from sealed vessel to rarefaction established by vacuum gauge and corresponding to specified partial pressure. Second component is supplied till atmospheric pressure is reached in vessel. EFFECT: diminished calibration time, reduced consumption and ejection of expansive and toxic gases, simplified design of plant to realize this procedure. 1 dwg
