Honeywell AWM43600V-2 Air Mass Flow Sensor

Honeywell AWM43600V-2 Air Mass Flow Sensor

The AWM43600V-2 belongs to the AWM40000 series of amplified microbridge mass flow sensors, which directly measure gas mass flow (not volumetric flow). It has a built-in signal conditioning circuit and provides an analog voltage output. It’s commonly used for monitoring the flow of clean gases like dry air and oxygen.
