Abstract

SE DESCRIBE UN DISPOSITIVO PARA LA COMPROBACION DE UN MEDIO LIQUIDO O GASEOSO, ESPECIALMENTE UN LIQUIDO LLENADO EN UN RECIPIENTE HASTA UNA DETERMINADA ALTURA. EL DISPOSITIVO CONTIENE AL MENOS UNA UNIDAD DE SENSORES (8, 10) QUE SE PONE EN CONTACTO CON UN MEDIO LIQUIDO O GASEOSO, QUE EN CASO DE UN INTERCAMBIO DE UN PRIMER MEDIO LIQUIDO O GASEOSO (P.EJ. AIRE) POR UN SEGUNDO MEDIO LIQUIDO O GASEOSO (P.EJ. LIQUIDO) A REGISTRAR EMITE UNA SEÑAL CORRESPONDIENTE. LA UNIDAD DE SENSORES PRESENTA UN ELEMENTO CALEFACTOR (8) Y UNA SONDA TERMICA (10). EL ELEMENTO CALEFACTOR (8) IRRADIA UN CALOR TAL Y LA SONDA TERMICA (10) ESTA DISPUESTA FRENTE A ESTE ELEMENTO CALEFACTOR (8), DE MODO QUE LA TEMPERATURA EXISTENTE EN LA SONDA TERMICA (10) Y LA MEDIDA POR ESTA ES INFLUIBLE POR EL ELEMENTO CALEFACTOR (8). DE ELLO RESULTA LA SEÑAL QUE INDICA QUE EL LIQUIDO HA SUBIDO HASTA UN DETERMINADO NIVEL, DE UNA MODIFICACION DE LA TEMPERATURA MEDIDA POR LA SONDA TERMICA (10).
