AWM2100V Airflow sensor, ±200 sccm

The micro-bridge air flow meter from the AWM2000 series is a passive device consisting of two Wheatstone bridges. The heating control circuit is required for operation in line with specifications. The sensor bridge supply voltage circuit is also required for operation in line with specifications. These two circuits are not integrated into the package and must be provided within the application. The differential amplifier is a useful interface for the sensor bridge. It can be used to provide output gain and introduces voltage offsets to the sensor output. Micro-bridge air flow meters from the AWM series are not designed to detect liquid flows, and will be damaged by liquid flowing through the sensor.

- Measuring capability in both directions - Air flow measured/actual value - Differential low pressure sensor
