Abstract

SE EXPONE UN DISPOSITIVO DE MEDICION PARA MEDIR LA DISTRIBUCION DE LA CONDUCTIVIDAD EN MEDIOS LIQUIDOS O EN FASES MULTIPLES QUE FLUYEN EN CUALQUIER DIRECCION. UN SENSOR DE REJILLA TIENE ELECTRODOS EN FORMA DE BARRAS O ALAMBRES PARALELOS ELECTROCONDUCTORES QUE FORMAN UNA REJILLA, SITUADOS EN DOS O TRES PLANOS Y AISLADOS ELECTRICAMENTE ENTRE SI Y DE SU MONTAJE. LOS ELECTRODOS DE CADA PLANO INDIVIDUAL SE ENCUENTRAN DESPLAZADOS ENTRE SI, PREFERENTEMENTE EN 90 . UNO DE LOS PLANOS, EL PLANO MEDIO CUANDO SE UTILIZAN TRES PLANOS, FORMA UN PLANO EXCITADOR CONECTADO A UN GENERADOR DE IMPULSOS, MIENTRAS QUE EL OTRO O LOS OTROS PLANOS FORMAN UNO O VARIOS PLANOS RECEPTORES ACOPLADOS A LA ELECTRONICA DE TRATAMIENTO. EN EL PROCESO DE GENERACION DE SEÑAL EXPUESTO, LOS ELECTRODOS DEL PLANO EXCITADOR SON ACCIONADOS SUCESIVAMENTE CON UN IMPULSO RECTANGULAR BIPOLAR SIMETRICO, Y TODOS LOS ELECTRODOS NO ACCIONADOS VAN CONECTADOS CON BAJA IMPEDANCIA AL POTENCIA CERO.
