AWM2100V Air Flow Sensor
FEATURES :
Bidirectional sensing capability
Actual mass air flow sensing
Low differential pressure sensing
The AWM2000 Series microbridge mass airflow sensor is a passive device com prised of two Wheatstone bridges. The heater control circuit in Figure 1 is re quired for operation per specifications. The sensing bridge supply circuit in Fig ure 2 is also required for operation per specifications. These two circuits are not on board the package and must be sup plied in the application. The differential amplifier in Figure 3 is a useful interface for the sensing bridge. It can be used to introduce the gain and to introduce volt age offsets to the sensor output as refer enced in Equation 1.
Note: For applications sensing hydrogen or helium, see Application Note 3, page 131.
