Honeywell Zephyr™ Digital Airflow Sensors are mass airflow sensors. They are used to determine the flow of air and other non-corrosive gases. The sensors are available in standard flow ranges. They are fully temperature calibrated and compensated with an onboard application specific integrated circuit (ASIC). These sensors provide a digital interface for high resolution and ease of integration to the application microprocessor. Additionally, a thermally isolated heater and temperature sensing element that Honeywell pioneered are used in these sensors.
