AWM3300V
FEATURES
ɀ Laser trimmed for improved sensor interchangeability ɀ Flow sensing up to 1.0 SLPM ɀ 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.
