The paper presents the results of the modeling and measurement study of the differential pressure transducer MP45 series made by the ValidyneTM Corp. This research is necessary during the construction of the device for identification of the human airducts model using the time method. The transducer parameters in the manufacturer's model are significantly different from the parameters calculated after the measurement study. This paper presents verification of models and frequency range of transducer. A new, more accurate model is proposed. The results obtained show that it is necessary to make a correction of the dynamic properties of this pressure sensor. The effects of this correction using first- and second-order correctors are presented and analyzed
