Honeywell airflow sensors contain a thin-film, thermally isolated bridge structure that consisting of heater and temperature sensing elements. This microbridge structure provides a sensitive and fast response to the flow, amount and direction of air or other gas over the chip and provides a proportional output voltage. State-of-the-art chip design and manufacturing techniques allow the microbridge to be remarkably sensitive, fast and small. Amplified versions provide a higher output signal and require less external circuitry while unamplified versions allow more options in external circuit deign. A variety of port styles provides greater application flexibility.

Best Used For:
HVAC system damper control, gas analysis, leak detection equipment, gas metering and chromatography, process control and vent hoods. Medical equipment applications such as respirators and ventilators, oxygen concentrators and anesthesia controllers.
