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
Datasheet:
| Product Category | Flow Sensor |
| Type | Mass Air Flow Sensor |
| Used for | Dry Gas |
| Range | +/- 1 L/min |
| Accuracy | 1% |
| Working power supply voltage | 8 V to 15 V |
Notes:
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.
4. Output load connected from VOUT to GND (current sinking).
5. Maximum allowable rate of flow change to prevent damage: 5.0 SLPM/1.0 sec.
* A 5 micron filter must be used on differential pressure sensors.
