Abstract

DISPOSITIVO ULTRASONICO PARA DETECTAR LAS CONCENTRACIONES DE SOLIDOS O LAS POSICIONES DE LAS SUPERFICIES DE CONTACTO SOLIDO/LIQUIDO EN MEDIOS LIQUIDOS, ESPECIALMENTE LIQUIDOS DE PROCESO DE BAYER. DICHO DISPOSITIVO COMPRENDE AL MENOS UN ELEMENTO PIEZOELECTRICO PROVISTO DE ELECTRODOS; ELEMENTOS DE CIRCUITO ELECTRICO CONECTADOS A DICHOS ELECTRODOS PARA TRANSPORTAR, CUANDO ESTAN CONECTADOS, SEÑALES ELECTRICAS DESDE Y HACIA UN APARATO DE CONTROL; UNA ENTANA TRANSPARENTE A LOS ULTRASONIDOS, HECHA DE CARBON VITREO, SITUADA ADYACENTE AL O A CADA UNO DE LOS ELEMENTOS PIEZOELECTRICOS; UNA MATRIZ PROTECTORA, PREFERIBLEMENTE DE RESINA EPOXIDICA, INCLUYENDO Y RODEANDO AL O A CADA ELEMENTO PIEZOELECTRICO Y A LOS ELECTRODOS, PERMITIENDO SIMULTANEAMENTE EL PASO DE LAS ONDAS ULTRASONICAS A TRAVES DE LA VENTANA O DE CADA VENTANA, HACIA O DESDE CADA ELEMENTO PIEZOELECTRICO; Y UNA CUBIERTA PROTECTORA EXTERNA, QUE COMPRENDE PREFERIBLEMENTE UN ELASTOMERO RESISTENTE AL ALCALI CAUSTICO Y QUE TIENE UNA SUPERFICIE NO POROSA, LISA, FORMANDO EL EXTERIOR DEL DISPOSITIVO, EXCEPTO EN LA ZONA DE LA O LAS VENTANAS. LA UTILIZACION DE CARBON VITREO EN DICHAS VENTANAS HACE QUE LAS SONDAS SEAN RESISTENTES A LA CORROSION Y A LA OXIDACION, SIN IMPEDIR LA EFECTIVIDAD DEL DISPOSITIVO. SE PROPORCIONA UNA MAYOR RESISTENCIA A LA OXIDACION, UTILIZANDO UN MATERIAL ELASTOMERICO, UTILIZADO PREFERENTEMENTE COMO CUBIERTA PROTECTORA EXTERNA.
