Abstract:A practical high gas temperature sensor is introduced, including overall structure design, sensitive element design, ceramic insulator selection, shield design and shell design aimed at a certain working condition. During key structure and size design of the shield, a model based on double heat conduction is put forward by which design method of high gas temperature sensor is optimized, then verification test of the design result has been carried out in the hot wind tunnel. Test result shows that the designed temperature sensor has a relative measuring error of 0.2%~1.3% and can be used for precise measurement of high gas temperature in aviation and aerospace fields.
