Abstract

LA PRESENTE INVENCION SE REFIERE A UN DISPOSITIVO DE MEDICION DE LA TEMPERATURA QUE REINA EN UNA ZONA A VIGILAR. ESTE DISPOSITIVO COMPRENDE UNA CADENA DE MEDICION (11, RI) ALIMENTADA BAJO UNA TENSION DE ALIMENTACION VO Y UN MEDIO DE TRATAMIENTO DE UNA SEÑAL DE MEDICION QUE COMPRENDE UN CONVERTIDOR ANALOGICO/NUMERICO (12). EL DISPOSITIVO SEGUN LA INVENCION SE CARACTERIZA EN QUE COMPRENDE ADEMAS, UNA PLURALIDAD DE RESISTENCIAS EN SERIE (R1...RI-1) COLOCADA EN LA CADENA DE MEDICION, Y UN MEDIO DE SELECCION (13) ADAPTADO PARA SELECCIONAR UNA TENSION DE REFERENCIA ENTRE UNA PLURALIDAD DE TENSIONES PRETOMADAS EN UN PUNTO DE LA PLURALIDAD DE RESISTENCIAS Y PARA EMITIR ESTA TENSION SELECCIONADA HACIA EL CONVERTIDOR. TAL DISPOSITIVO PERMITE MEDIR UNA TEMPERATURA SOBRE UNA ZONA EXTENDIDA, EFECTUANDO CAMBIOS DE TENSIONES DE REFERENCIA SIN PERTURBAR LAS CURVAS DE CONVERSION DEL CONVERTIDOR.
