AWM43600V-2

AWM43600V-2 is an AWM40000 series amplified airflow sensor. It is based on proven microbridge technology and includes an unamplified sensor-only and amplified signal conditioned device. 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. Potential application includes respirators and ventilators, oxygen concentrators and conservers, anaesthesia machines (medical), HVAC damper control, gas analysers, low vacuum control, process control, leak detection equipment, vent hoods, gas metering, chromatography.
