This study delves into the modelling of resistance wire thermometers (RWTs) within the application context of measuring the exhaust gas temperature pulse in internal combustion engines. The model was developed in a commercial simulation software utilizing the heat balance equation. Disparities were found between different model representations of the prongs due to differences in the heat transfer within the sensor, which impacts its expected dynamic response. The appropriate modelling choice will be made upon validation with shock tube experiments for different RWT designs.
