Abstract

EL APARATO COMPRENDE UNA UNIDAD DE CONDUCCION Y UNA UNIDAD DE GENERACION DE TENSION. LA UNIDAD DE CONDUCCION INCLUYE UN ELECTRODO VISUALIZADOR Y OTRO DE DATOS QUE SE DIRIGEN A UN ELECTRODO MATRIZ FORMADO POR LOS VISUALIZADORES Y DE DATOS. LA UNIDAD DE GENERACION INCLUYE MEDIOS DE GENERACION MIXTA, Y MEDIOS DE GENERACION DE UNA TENSION EN CURSO PARA SUMINISTRO DE TENSIONES DE CONDUCCION QUE CONDUZCAN AL ELECTRODO MATRIZ, MEDIOS QUE GENERAN UNA TENSION IGUAL A LA DIFERENCIA ENTRE LA TENSION EN CURSO EN LA TENSION MIXTA. LAS TENSIONES SE CONTROLAN EN FUNCION DE LA TEMPERATURA.
