Abstract

SE DESCRIBE UN PROCESO PARA MEDIR EL FLUJO DE AIRE EN, POR EJEMPLO, LOS CONDUCTOS DE ENTRADA DE AIRE EN VEHICULOS MOTORIZADOS, USANDO UN SENSOR DE CALOR (8) INSTALADO SOBRE UN SUSTRATO (1). ESTE SENSOR ESTA AISLADO TERMICAMENTE DEL SUSTRATO Y EL FLUJO DE CALOR (Q SUB 3, Q SUB 4) QUE PASA POR EL SENSOR SE DETERMINA Y/O MODIFICA Y SE USA PARA CORREGIR LA SEÑAL DEL SENSOR.
