FEATURES

HonEywEll ZEpHyR™ AiRFlow SEnSoRS

HAF Series-High Accuracy.

±50 SCCM to ±750 SCCM

Features: Total Error Band (TEB) as low as±0.25 %FSS • Fast response time

• Wide range of airflows • Customizable flow ranges and configurable package

styles • Full calibration and temperature compensation • High sensitivity at very

low flows • Linear output • High stability • Low pressure drop • High 12-bit

resolution (digital), 0.039 %FS resolution (analog) • Low 3.3 Vdc operating

voltage • ASIC-based I2C output compatibility (digital)

• Insensitivity to mounting orientation • Insensitivity to altitude • Small size

• RoHS-compliant materials 

Benefits: Total Error Band (TEB) as low as ±0.25 %FSS allows for precise airflow

measurement, often ideal for demanding applications with high accuracy

requirements. Fast response time allows a customer’s application to respond

quickly to airflow change, important in critical medical (e.g., anesthesia) and

industrial (e.g., fume hood) applications. Measures mass flow at standard flow

ranges of ±50. ±100. ±200. ±400 or ±750 SCCM, or custom flow ranges,

increasing the options for integrating the sensor into the application.
