AWM43300V | Honeywell

Flow sensor, AWM43300V, Honeywell

The microbridge mass airflow sensor operates on the theory of heat transfer. Mass airflow is directed across the surface of the sensing elements. Output voltage varies in proportion to the mass air or other gas flow through the inlet and outlet ports of the package.

This sensor has a unique silicon chip based on advanced microstructure technology. It consists of a thin film, thermally-isolated bridge structure containing heater, and temperature sensing elements. The bridge structure provides a sensitive and fast response to the flow of air or other gas over the chip.
