DESCRIPTION

· Honeywell Zephyr™ HAF Series sensors offer a digital interface for airflow measurement across various full-scale flows and temperature ranges.

· Utilizes thermally isolated heater and temperature sensing elements for rapid response to air or gas flow.

· Designed to measure mass flow of air and non-corrosive gases with standard flow ranges from 10 SLPM to 300 SLPM.

· Features onboard ASIC for full calibration and temperature compensation, operating from 0°C to 50°C.

· Employs MEMS technology with platinum and silicon nitride thin films for precise airflow measurement.

· Ensures reliability, accuracy, and customizable options, adhering to ISO 9001 standards.

FEATURES

· Fast response time of 1 ms suitable for critical applications like medical anesthesia and industrial fume hoods.

· High stability minimizes thermal errors and null shift, reducing the need for frequent recalibrations.

· High sensitivity at low flows ensures quick detection of flow initiation or cessation.

· 12-bit resolution enhances the detection of minor airflow changes for precise control.

· Broad airflow range with standard and custom options for versatile application integration.

· Multiple port styles available for flexible pneumatic connections.

· Linear output simplifies signal interpretation, aiding in cost and design efficiency.
