Measuring element for mass airflow sensor

摘要

The measuring element has at least one pair of thin-film heating resistances (1,2) applied to the surface of a substrate (4) to lie next to one another in the airflow direction. The substrate also supports at least one pair of thin-film ambient air temp. detection resistances (3a,3b) offset from the heating resistances perpendicular to the air flow direction, with electrode terminals (6a,..6f) for providing signals from both sets of resistances arranged along one edge of the substrate.
