Abstract
LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO DE MEDICION DE LA TEMPERATURA MEDIANTE UN SENSOR (10) CON COEFICIENTE DE TEMPERATURA NEGATIVO. ESTE SENSOR ESTA ASOCIADO A UNA ETAPA DE TRATAMIENTO (11) DE LA SEÑAL QUE INCLUYE AL MENOS UN TRANSISTOR (T) MONTADO EN PARALELO CON AL MENOS UNA RESISTENCIA (R1, R1A....R1N1) DENOMINADA DE "PULL UP". UN CONVERTIDOR ANALOGICO/DIGITAL (13) RECIBE UNA TENSION (VBO, VB1) TOMADA EN UN PUNTO MEDIO ENTRE EL SENSOR (10) Y LAS RESISTENCIAS DE "PULL UP". EL PROCEDIMIENTO SE CARACTERIZA PORQUE CONSISTE EN: CONTROLAR EL TRANSISTOR (T) SEGUN UNA TENSION DENOMINADA CUADRADA DE TAL MANERA QUE EL TRANSISTOR ESTE ALTERNATIVAMENTE Y DE MANERA REGULAR EN POSICION DE CONDUCTOR Y DESPUES EN POSICION BLOQUEADA; MEDIR EL VALOR DE LA TENSION V{SUB,RT} EN UNA ENTRADA ANALOGICA (12) DEL CONVERTIDOR (13) CUANDO EL TRANSISTOR (T) ES CONDUCTOR Y CUANDO EL TRANSISTOR ESTA BLOQUEADO; DETERMINAR A PARTIR DE ESTAS DOS MEDICIONES LA TENSION DE SATURACION (VCE) DEL TRANSISTOR, DEDUCIR EL VALOR DE LA TENSION CORREGIDA (N0, N1) Y DEDUCIR LA TEMPERATURA QUE REINA ALREDEDOR DEL SENSOR (10). LA PRESENTE INVENCION SE REFIERE TAMBIEN A UN DISPOSITIVO QUE UTILIZA TAL PROCEDIMIENTO Y SE APLICA MAS EN PARTICULAR AL CAMPO DE LA ELECTRONICA DEL AUTOMOVIL.
