Product Specification

Honeywell Zephyr™

Analog Airflow Sensors

HAF Series–High Accuracy
±50 SCCM to ±750 SCCM


Honeywell Zephyr™ HAF Series sensors provide an analog 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 available at ±50, ±100, ±200, ±400 or ±750 SCCM. Custom flow ranges are also available. The sensors are fully calibrated and temperature compensated with an onboard Application Specific Integrated Circuit (ASIC).

 

The HAF Series is compensated over the temperature range of 0 ℃ to 50 ℃ [32 ℉ to 122 ℉] and operates across a temperature range of -20 ℃ to 70 ℃ [-4 ℉ to 158 ℉]. The state-of-the-art ASIC-based compensation provides analog outputs with a response time of 1 ms.
