Go with the flow of engineering leadership. All airflow sensors operate on heat transfer — flow and differential pressure.
But Honeywell Sensing and Control (S&C) offers advanced chip design, manufacturing techniques and microstructure technology, allowing their microbridge to be notably faster, smaller and more sensitive. Honeywell's silicon chip design is created from a thinfilm, thermally isolated bridge structure, containing both heater and temperature sensing elements. This provides rapid response to the air or gas flow and amount and direction, delivering a proportional output voltage.
Amplified versions provide an enhanced output signal and less external circuitry, while unamplified versions allow additional external circuit options. What’s more, a variety of port styles provides greater application flexibility.
