Abstract
DISPOSITIVO DE CIRCUITO ELECTRONICO EN UN CIRCUITO DE MEDICION DE TEMPERATURA BASADO EN UNA RESISTENCIA DE PLATINO (PT) COMO UNA RESISTENCIA DE MEDICION DE LA TEMPERATURA, POR MEDIO DEL CUAL ADEMAS DE LA RESISTENCIA DE PLATINO SE PROPORCIONA UNA RESISTENCIA DE REFERENCIA (R1). EL CIRCUITO DE MEDICION (S) SE ADAPTA PARA APLICAR CORRIENTES DC GRANDES IGUALES (I5,I6) A AMBAS RESISTENCIAS QUE TIENEN UN CONDUCTOR DE RETORNO COMUN (3) DESDE ESTAS, Y PARA MEDIR LA DIFERENCIA DE VOLTAJE RESULTANTE (U) A LO LARGO DE LAS RESISTENCIAS. POR MEDIO DE AL MENOS UN AMPLIFICADOR OPERACIONAL (G) LA DIFERENCIA DE VOLTAJE SE ADAPTA PARA PROVOCAR UNA CORRIENTE DC DE SALIDA DESDE EL CIRCUITO DE MEDICION (S) QUE ES PROPORCIONAL A LA DIFERENCIA DE VOLTAJE Y MEDIANTE ESTO CONSTITUIR UNA MEDICION DE LA TEMPERATURA DE LA RESISTENCIA DE PLATINO (PT). EL CIRCUITO DE MEDICION (S) CONSTA DE MEDIOS PARA COMPENSAR LA NO LINEARIDAD DE LA RESISTENCIA-TEMPERATURA CARACTERISTICA DE LA RESISTENCIA DE PLATINO. SE PROPORCIONAN DOS TRANSISTORES (T1,T2), DE CADA UNO DE LOS CUALES SE ADAPTAN LAS CORRIENTES DE SALIDA DEL COLECTOR (I3,I4) PARA AÑADIRSE A SU CORRIENTE DC GRANDE IGUAL RESPECTIVA (I6,I5) QUE SE APLICA A LA RESISTENCIA DE PLATINO (PT) Y LA RESISTENCIA DE REFERENCIA (R1) RESPECTIVAMENTE. EL VOLTAJE BASE DE EMISOR DE LOS TRANSISTORES SE ADAPTA PARA VARIAR DEPENDIENDO DE LA CORRIENTE DC DE SALIDA DESDE EL CIRCUITO DE MEDICION (S).
