Abstract

UN TRANSDUCTOR DE INDUCTANCIA VARIABLE LINEAL EN EL QUE UN EMBOLO IMPULSADO POR UN MUELLE QUE CONTIENE UN NUCLEO MAGNETICO SE MUEVE AXIALMENTE EN UN ALOJAMIENTO ESTANCIONARIO QUE CONTIENE UN CONJUNTO DE BOBINA TIENE LA SUPERFICIE EXTERIOR DEL EMBOLO (1) HECHA DE UN MATERIAL CERAMICO GUIADO LINEALMENTE PARA DESLIZARSE EN UN CASQUILLO CERAMICO (2) EN EL ALOJAMIENTO. EL CASQUILLO PUEDE ESTAR EMBRIDADO PARA FORMAR UNA BOBINA PARA EL CONJUNTO DE LA MISMA.
