Temperature sensor for an airflow

摘要

A temperature sensor for an airflow is proposed, especially for the airflow in an electronically controlled heating and/or air conditioning installation of motor vehicles, the air current (11) being guided in a channel (10) in which air masses of different temperature and different flow speeds (A, B) occur at different places on the channel cross-section. To detect the air temperature, taking into account the flow rate, a temperature-dependent resistor (13) is arranged in the airflow (11) in such a way that it detects the average value of the air temperature, as an integrating sensor. <IMAGE>
