Abstract

SE DESCRIBE UN CIRCUITO DE REGULACION Y EVALUACION PARA UN SENSOR DEL CALOR DE REACCION, EL CUAL TIENE UN CIRCUITO EN SERIE DE UNA RESISTENCIA DE MEDICION Y DE UNA RESISTENCIA DE REFERENCIA, LAS CUALES SON DEPENDIENTES DE LA TEMPERATURA. A TRAVES DE LAS DOS RESISTENCIAS SE CONDUCE UNA CORRIENTE ALTERNA CONSTANTE Y LAS DOS RESISTENCIAS SE CALIENTAN CON AYUDA DE UN CALENTADOR (13). POR VALORACION DE LA CAIDA DE TENSION EN LA RESISTENCIA DE REFERENCIA, SE REGULA EL CALENTADOR (13) DE TAL FORMA QUE EL VALOR DE LA RESISTENCIA DE REFERENCIA Y CON EL SU TEMPERATURA SIEMPRE PERMANEZCA IGUAL. CON ESTO ESTA ASEGURADO QUE TAMBIEN LA TEMPERATURA DE LA RESISTENCIA DE MEDICION PERMANECERA CONSTANTE, CUANDO NO TENGAN LUGAR REACCIONES QUE CAUSEN CALOR. EN CAMBIO CUANDO SE PRESENTAN TALES REACCIONES, SE AUMENTA LA TEMPERATURA DE LA RESISTENCIA DE MEDICION (11), CON LO CUAL SE MODIFICA LA CAIDA DE TENSION QUE SE PRESNTA EN LA RESISTENCIA DE MEDICION, SE EVALUA ESTA CAIDA DE TENSION Y ESTA CAIDA ES DIRECTAMENTE UNA DIMENSION DEL CALOR GENERADO POR LAS REACCIONES DEL GAS.
