Intake Air Temperature Sensor and Thermal Airflow Meter Including the Same |
摘要 |
An intake air temperature sensor capable of detecting an intake air temperature highly accurately and at high speed. The intake air temperature sensor of the present invention includes: a secondary passage 7 taking in an intake airflow; a flow rate detecting element 13 disposed in the secondary passage 7; an intake air temperature detecting element 4 provided outside the secondary passage; a temperature sensor 9 detecting a temperature of a fitting section of the intake air temperature detecting element 4; a circuit board 11 disposed in a casing; and an integrated circuit 10 applying a correction process to an output of the intake air temperature detecting element 4 on the basis of signals output from the temperature sensor 9 and a flow rate detecting element 13.
