Abstract

ELEMENTO SENSOR PARA SENSORES DE CORRIENTE LIMITE PARA LA DETERMINACION DEL VALOR DE MEZCLAS GASEOSAS, QUE PRESENTA EN UN CANAL DE DIFUSION (7) AL MENOS DOS ELECTRODOS DE BOMBEO (8 Y 8''), INTERNOS DISPUESTOS UNO ENFRENTE DEL OTRO. DE MODO QUE SE REDUCE CLARAMENTE LA POLARIZACION INVONVENIENTE DE LOS ELECTRODOS, QUE SE PRESENTA FACILMENTE, EN LOS ELEMENTOS SENSORES CON TAN SOLO UN ELECTRODO INTERNO DE BOMBEO. AL MISMO TIEMPO SE CONSIGUE MEJOR APROVECHAMIENTO DEL METAL NOBLE NECESARIO PARA LA CONFIGURACION DE LOS ELECTRODOS DE BOMBEO.
