The Honeywell product line of airflow sensors operate on heat transfer - flow and differential pressure, and come in a variety of port styles for flexible application and use. The airflow sensors feature state of the art manufacturing and microstructure technology -- advanced silicon chip design, with its thin-film material and thermally isolated bridge structure. Heat and temperature sensors allow for quick, enhanced response time to air and gas flow, amount, and direction, therefore minimizing power consumption while delivering significant voltage output. Amplified versions of the products provide an enhanced output signal and less external circuitry, while unamplified versions allow option for additional external circuitry.
