Product Specification
AWM3300V Airflow Sensors Microbridge Mass Airflow/Amplified：
Like the AWM2000 Series, the dual Wheatstone bridges control airflow measurement. The AWM3000 Series is amplified; therefore, it can be used to increase the gain and to introduce voltage offsets to the sensor output.
AWM3300V Airflow Sensors Features：
? Laser trimmed for improved sensor interchangeability
? Flow sensing up to 1.0 SLPM
? Low differential pressure sensing

1. Initial warm-up time for signal conditioned circuitry is 1 minute max.
2. Output Voltage is ratiometric to supply voltage.
3. Temperature shifts when sensing differential pressure correlates to the density change of the gas over temperature. (See Application Note 1.)
4. Maximum allowable rate of flow change to prevent damage: 5 SLPM/1 sec.
