Airflow Sensors Line Guide


Airflow Sensors

All airflow sensors operate on heat transfer — flow and differential pressure. 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.

Honeywell offers:

  • Advanced chip design, manufacturing techniques and microstructure technology
  • Enhanced response time and low power consumption
  • Variety of port styles provide greater application flexibility
