Abstract

UN SISTEMA MULTICANAL DE DETECCION DE TEMPERATURAS REMOTAS TIENE UN CONJUNTO DE TEMPERATURAS DE REFERENCIA PARA LAS CONEXIONES (12) DE REFERENCIA DE UNA PLURALIDAD DE TERMOPARES PARA DETERMINAR TEMPERATURAS EN PUNTOS REMOTOS (10). EL CONJUNTO COMPRENDE UN SISTEMA DE COMPONENTES (2), CADA UNO ADAPTADO A ESTABLECER CONTACTO TERMICO CON UNA CONEXION (12) DE REFERENCIA DE UN TERMOPAR DE DETECCION DE TEMPERATURAS REMOTAS, UN TERMOMETRO (1) DE REFERENCIA ABSOLUTA, SITUADO DENTRO DEL SISTEMA PARA MEDIR UNA TEMPERATURA DE REFERENCIA ABSOLUTA Y UN TERMOPAR PARA DETECTAR UNA DIFERENCIA DE TEMPERATURAS ENTRE EL TERMOMETRO (1) DE REFERENCIA Y UN COMPONENTE DEL SISTEMA (2X). UN MEDIO DE PROCESAMIENTO DE DATOS (20) CALCULA LA TEMPERATURA DEL COMPONENTE (2X) DEL SISTEMA DESDE LA TEMPERATURA DE REFERENCIA ABSOLUTA Y LA DIFERENCIA DE TEMPERATURAS. LOS TERMOPARES DE DETECCION DE DIFERENCIAS DE TEMPERATURAS PUEDEN NO ESTAR EN CONDICIONES DE MEDIR LAS TEMPERATURAS DE ALGUNOS DE LOS COMPONENTES (2) DEL SISTEMA,ESTANDO INTERPOLADAS LAS TEMPERATURAS DE TALES COMPONENTES (2) POR EL MEDIO (20) DE PROCESAMIENTO DE DATOS DESDE LAS DIFERENCIAS DE TEMPERATURAS MEDIDAS.
