Honeywell AIDC Honeywell AIDC AWM3300V Microbridge Mass Airflow Sensor

Applications· Damper control for heating, ventilation, and air conditioning systems· Gas analysers· Low vacuum control· Process control· Medical respirators and ventilators· Oxygen concentrators· Leak detection equipment· Vent hoods· Anesthesia control· Gas metering· Gas chromatographyOperating principleThe microbridge mass airflow sensor operates on the theory of heat transfer. Massairflow 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 portsof the package. The specially designed housing precisely directs and controlsthe airflow across the microstructure sense element. Mechanical design of thepackage allows it to be easily mounted to printed circuit boards.The microbridge mass airflow 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 prov...
