Abstract

YA SE CONOCE UN SENSOR LWL PARA FUERZAS DE TRACCION CON POR LO MENOS UNA VUELTA DE HILO METALICO O DE VIDRIO BOBINADO POR EL LWL Y POR TANTO CON UNA ENVOLTURA EN FORMA DE ALAMBRE RESISTENTE A LA TRACCION DE PLASTICO REFORZADO CON FIBRA DE VIDRIO. EL JUEGO DE PARAMETROS LWL - ALAMBRE - ENVOLTURA ES DIFICIL Y SOLO SE PUEDE REPRODUCIR CON GRAN DIFICULTAD DE FORMA QUE LA FABRICACION DE UN SENSOR DE ESTAS CARACTERISTICAS ES MUY COSTOSA. POR LO TANTO EXISTE LA TAREA DE FORMAR EL SENSOR LWL DE TAL MANERA QUE SU FABRICACION SEA MAS FACIL PERO TAMBIEN SU SENSIBILIDAD DE MEDICION AUMENTE. LA SOLUCION CONSISTE ESENCIALMENTE EN BOBINAR VARIAS VUELTAS POR EL LWL (1) PREFERENTEMENTE DOS VUELTAS (2, 2) DE ALAMBRE DE ACERO DE FORMA CRUZADA. ESTE ALMA DE SENSOR SE OCUPA DE LA FUNCION DE SENSOR CASI SOLO DE FORMA QUE LA ENVOLTURA (3) APENAS AYUDA Y POR TANTO PUEDE FORMARSE SEGUN LAS DEMAS REQUERIMIENTOS. UN SENSOR LWL DE ESTAS CARACTERISTICAS SIRVE SOBRE TODO COMO SENSOR DE DILATACION DE MAYOR SENSIBILIDAD PARA EL CONTROL DE EDIFICIOS Y OBRAS DE CONSTRUCCION. PARA ELLO LA UNICA FIGURA.
