N2 AWM3000 Gas Mass Air flow Sensor AMW3303V 3 Pin Heater Control Circuit

Product Description
AMW3303V Flow Sensor Mass N2 3-Pin Heater Control Circuit



FEATURES

* Laser trimmed for improved sensor interchangeability *Flow sensing up to 1.0 SLPM * Low differential pressure sensing



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. The schematic in Figure 3 depicts the amplification circuitry on board the sensor. Also, the heater control circuit (see Figure 1) and the sensing bridge supply circuit (see Figure 2) are on board the package
