Honeywell's Zephyr™ Analog and Digital Airflow Sensors: HAF Series-High Accuracy sensors provide an analog or digital interface for reading airflow over the specified full-scale flow span and temperature range. The thermally isolated heater and temperature sensing elements help these sensors provide a fast response to air or gas flow.
Zephyr sensors are designed to measure mass flow of air and other non-corrosive gases. Standard flow ranges are available 750 SCCM. The sensors are fully calibrated and temperature compensated with an onboard Application Specific Integrated Circuit (ASIC).
