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 °C to 50 °C [32 °F to 122 °F] and operates across a temperature range of -20 °C to 70 °C [-4 °F to 158 °F]. The state-of-the-art ASIC-based compensation provides analog outputs with a response time of 1 ms. These sensors operate on the heat transfer principle to measure mass airflow. They consist of a microbridge Microelectronic and Microelectromechanical System (MEMS) with temperature-sensitive resistors deposited with thin films of platinum and silicon nitride. The MEMS sensing die is located in a precise and carefully designed airflow channel to provide repeatable response to flow. Zephyr sensors provide the customer with enhanced reliability, high accuracy, repeatable measurements and the ability to customize sensor options to meet many specific application needs. The combination of rugged housings with a stable substrate makes these products extremely robust. They are designed and manufactured according to ISO 9001 standards What makes our sensors better?

Wide range of airflows* Zephyr 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. Customizable flow ranges and configurable package styles* Meet specific end-user needs. FULL CALIBRATION AND TEMPERATURE COMPENSATION Typically allow customer to remove additional components associated with signal conditioning from the PCB, reducing PCB size as well as costs often associated with those components (e.g., acquisition, inventory, assembly). LINEAR OUTPUT* Provides more intuitive sensor signal than the raw output of basic airflow sensors, which can help reduce production costs, design, and implementation time. Low pressure drop* Typically improves patient comfort in medical applications, and reduces noise and system wear on other components such as motors and pumps. 0.049 %FS resolution Increases ability to sense small airflow changes, allowing customers to more precisely control their application. Low 3.3 Vdc operating voltage option and low power consumption Allow for use in battery-driven and other portable applications. Small size Occupies less space on PCB, allowing easier fit and potentially reducing production costs; PCB size may also be reduced for easier fit into space-constrained applications. RoHS-compliant materials Meet Directive 2002/95/EC. *Competitive Differentiator sensing.honeywell.com 3 Potential Applications MEDICAl Anesthesia Delivery machines Ventricular Assist Devices (Heart Pumps) Nebulizers Oxygen concentrators Patient monitoring systems (respiratory monitoring) Sleep apnea machines Spirometers Ventilators LAPAROSCOPY INDUSTRIAL AIR-TO-FUEL RATIO FUEL CELLS GAS LEAK DETECTION VAV SYSTEM ON HVAC SYSTEMS GAS METERS HVAC FILTERS 4 sensing.honeywell.com ±50 SCCM to ±750 SCCM Table 1.

Contact Honeywell for details. 3 Accuracy: The maximum deviation from the nominal output over the compensated flow range at a reference temperature of 25 °C. Errors include offset, span, non-linearity, hysteresis and non-repeatability. 4 Full Scale Span (FSS): The algebraic difference between the output at the forward Full Scale (FS) flow and the output at the reverse FS flow. Forward flow is defined as flow from P1 to P2 as shown in Figure 9.

Includes all errors due to offset, full scale span, flow hysteresis, flow repeatability, thermal effect on offset, thermal effect on span and thermal hysteresis. 6 Null accuracy: The maximum deviation in output at 0 SCCM from the ideal transfer function over the compensated temperature range. This includes offset errors, thermal airflow hysteresis and repeatability errors. 7 Response time: The time to electrically respond to any mass flow change at the microbridge airflow transducer (response time of the transducer may be affected by the pneumatic interface). 8 Warm-up time: The time to the first valid flow measurement after power is applied. 9 Default calibration media is dry nitrogen gas.
