Honeywell AWM43300V Air Flow Sensor +1000sccm Female, 0.19″ (4.826mm) Plastic
The Honeywell AWM43300V Air Flow Sensor is part of the AWM40000 series, designed using advanced microbridge technology to provide accurate and reliable measurement of gas flow up to ±1000 sccm. It operates based on thermal mass flow sensing, where airflow passing over a heated microstructure causes a temperature difference that is converted into a proportional electrical output. This design ensures high sensitivity, fast response, and excellent repeatability, making it suitable for precision applications.
The sensor integrates signal conditioning circuitry, delivering a calibrated analog voltage output proportional to the airflow rate. Its compact plastic housing with female ports allows easy installation into airflow systems and tubing. With low power consumption and stable performance across temperature variations, the AWM43300V is widely used in medical instrumentation, gas analysers, and environmental monitoring systems requiring accurate and consistent airflow measurement.
