All airflow sensors operate on heat transfer — flow and differential pressure.
We offer airflow sensors from Honeywell. Silicon chip design is created from thin-film, 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.
