Abstract
SE PRESENTA UN SENSOR DE CONDUCTIVIDAD INDUCTIVO (10) QUE SE ENCUENTRA INMERSO EN UN LIQUIDO PARA MEDIR SU CONDUCTIVIDAD. EL SENSOR (10) COMPRENDE UN TRANSDUCTOR (18, 20, 22) PARA GENERAR UN CAMPO MAGNETICO CAMBIANTE Y PARA MEDIR DE FORMA INDUCTIVA UNA CORRIENTE ELECTRICA INDUCIDA EN EL LIQUIDO MEDIANTE EL CAMPO MAGNETICO CAMBIANTE. EL TRANSDUCTOR (18, 20, 22) TIENE UNA SUPERFICIE EXTERNA QUE MIRA HACIA EL LIQUIDO. UNA MEMBRANA ELASTICA (30) SEPARA LA SUPERFICIE EXTERNA DEL LIQUIDO. LA MEMBRANA ELASTICA (30) SE HINCHA DE FORMA PERIODICA Y SE DESINFLA PARA DEFORMAR SU FORMA EXTERIOR Y POR LO TANTO REMOVER LOS DEPOSITOS FORMADOS SOBRE LA MEMBRANA 30.
