Abstract

COLOCACION DE INTERRUPTOR PARA CONTROL DE LA PROVISION DE TINTA EN DISPOSITIVOS DE IMPRESION DE TINTA CON AYUDA DE TRES ELECTRODOS COLOCADOS EN EL DEPOSITO PROVEEDOR DE TINTA, DE LOS QUE UN PAR DE ELECTRODOS SIRVEN PARA LA TOMA DE UNA RESISTENCIA COMPARATIVA ESPECIFICA DE LIQUIDO Y LOS OTROS ELECTRODOS SIRVEN CON UNO DE LOS OTROS DOS ELECTRODOS PARA TOMA DE RESISTENCIA VARIABLE CON DEPENDENCIA DEL FLUVIOMETRO DE LIQUIDO. EN DOS ELECTRODOS SE COLOCAN IMPULSOS DE TENSION CONTINUA DE SIGNO CONTRARIO; EN EL TERCER ELECTRODO SE ENGRANA UN NIVEL DE RELLENO DE LA TENSION CORRESPONDIENTE AL DEPOSITO DE PROVISION DE TINTA, QUE SE VALORA COMO CRITERIO PARA ACTIVACION DE UN DISPOSITIVO INDICADOR DEL FINAL DE PROVISION DE TINTA Y/O PARA CONECTAR EL DISPOSITIVO DE IMPRESION DE TINTA.
