Abstract
APARATO PARA LA MEDICION DE FLUJO TERMICO EN UN CUERPO CONDUCTOR DEL CALOR. COMPRENDE UN DISPOSITIVO DETECTOR DE DIFERENCIAS DE TEMPERATURA, QUE SE MONTA EN EL INTERIOR DEL CUERPO CONDUCTOR PARA QUE PROPORCIONE UNA SEÑAL REPRESENTATIVA DE LA DIFERENCIA DE TEMPERATURAS EXISTENTES ENTRE DOS ZONAS ADYACENTES DE DICHO CUERPO, ESTANDO FORMADO DICHO DISPOSITIVO POR UN PRIMER PAR DE DETECTORES DE TEMPERATURA (30, 32) SITUADOS, CADA UNO DE DICHOS DETECTORES, EN UNA DE LAS ZONAS ADYACENTES DEL CITADO CUERPO, Y POR UN SEGUNDO PAR DE DETECTORES DE TEMPERATURA (34, 36) COLOCADOS EN SERIE CON EL PRIMER PAR DE DETECTORES (30, 32). DICHOS DETECTORES DE TEMPERATURA (30, 32, 34, 36) ESTAN CONSTITUIDOS POR UNIONES CALIENTES Y FRIAS DE TERMOPARES. DE APLICACION EN UN REACTOR CON AGUA A PRESION.
