Abstract
DISPOSITIVO PARA DETECTAR EL NIVEL DE UN LIQUIDO EN UN DEPOSITO, EN PARTICULAR DE UN GAS LICUADO EN UN DEPOSITO DE ENCENDEDOR. CONSTA DE UN HAZ DE FIBRAS OPTICAS (2), ALOJADO EN UNA VAINA RIGIDA (3), QUE TIENE UNA DE SUS EXTREMIDADES (5) DISPUESTA EN EL DEPOSITO, SENSIBLEMENTE AL NIVEL A DETECTAR, ESTANDO DOTADA CON UN ELEMENTO DIOPTRICO (7), MIENTRAS QUE SU OTRA EXTREMIDAD (5 ELEVADO ,) ESTA FIJADA SOBRE EL FONDO (11) DEL ENCENDEDOR. EL ELEMENTO DIOPTRICO ESTA CONSTITUIDO POR UN CONO (7), FORMADO POR MOLDEO SOBRE UN TAPON DE PLEXIGLAS QUE CORONA LA EXTREMIDAD DEL HAZ DE FIBRAS (2) Y DE LA VAINA RIGIDA (3). CUANDO EL CONO (7) NO ESTA SUMERGIDO LOS RAYOS LUMINOSOS QUE LLEGAN POR LAS FIBRAS 89) SITUADAS A LA ALTURA DE DICHO CONO SUFREN UNA DOBLE REFLEXION TOTAL SOBRE LAS CARAS DEL MISMO, POR EL CONTRARIO, CUANDO EL CONO ESTA SUMERGIDO LOS RAYOS NO SUFREN REFLEXION TOTAL.
