Abstract

UN DETECTOR DE LA HUMEDAD DEL SUELO (10) QUE HACE USO DE UNOS ELECTRODOS DETECTORES (12, 14) CADA UNO DE LOS CUALES TIENE UNA CAPACITANCIA MAYOR PARA UNA SENSIBILIDAD REDUCIDA A LA RESISTENCIA DEL SUELO Y UNA SENSIBILIDAD AUMENTADA A LA HUMEDAD DEL SUELO QUE RODEA AL ELECTRODO. EL DETECTOR DE LA HUMEDAD DEL SUELO TIENE UN PAR DE VARILLAS CILINDRICAS CADA UNA DE LAS CUALES ESTA REVESTIDA CON UNA CAPA DELGADA DE MATERIAL DIELECTRICO (17), QUE SE ENTIERRAN EN EL SUELO U OTRO MEDIO Y SE CONECTAN A UN CIRCUITO DE CONVERSION EN EL QUE LOS ELECTRODOS ACTUAN A MODO DE CAPACITANCIA VARIABLE. LA CAPACITANCIA DESARROLLADA POR CADA UNO DE LOS ELECTRODOS DETECTORES ESTA RELACIONADA CON LA HUMEDAD PRESENTE EN EL SUELO QUE RODEA A LOS ELECTRODOS. LAS PARTICULAS DEL SUELO EN CONTACTO CON LOS ELECTRODOS DESARROLLAN UN AREA CONDUCTORA EFECTIVA Y ESTO DETERMINA EL VALOR DE LA CAPACITANCIA VARIABLE PRESENTADO AL CIRCUITO DE CONVERSION.
