Honeywell's Zephyr™ Digital Airflow Sensors: HAF Series-High Accuracy, provide a digital interface for reading airflow over specified full-scale flow and compensated temperature ranges. 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 10 SLPM, 15 SLPM, 20 SLPM, 50 SLPM, 100 SLPM, 200 SLPM or 300 SLPM. The sensors are fully calibrated and temperature compensated with an onboard Application Specific Integrated Circuit (ASIC).
