Abstract

Se describe un sensor para detectar propiedades quimicas de un liquido, por ejemplo en un pozo de petroleo, que incluye un electrodo de vidrio de pH (22a) y un electrodo de referencia (22c). El electrodo de vidrio (22a) consiste de un electrodo sensor angosto (30) en la superficie de un sustrato electricamente aislante (20), una capa de vidrio (36) que cubre el electrodo sensor (30), y dos electrodos de limpieza (32, 33) que se extienden uno a lo Largo de cada lado del electrodo sensor a lo largo de su longitud completa de deteccion. Los electrodos de limpieza (32, 33) no estan cubiertos por la capa de vidrio, y no estan mas de 3 mm espaciados uno del otro. La aplicacion de un voltaje entre ellos genera burbujas de gas mediante electrolisis que desalojan cualquier ensuciamiento del electrodo de vidrio (22a). El electrodo sensor (30) puede ser de forma de zigzag, con los electrodos de limpieza (32, 33) entrelazados entre las partes sucesivas del zigzag. Una membrana hidrofilica (24) de PVdF de microporos sulfonados proporciona proteccion adicional contra ensuciamiento de los electrodos (22) por petroleo. Esto proporciona un sensor compacto, en estado solido, que puede ser limpiado in situ.
