Why are they named Zephyr?–
zeph•yr
(zĕf′ər) is defined as:•
Breeze•
Gentle wind•
Air•
Greek mythology: the Greek god of the west wind
–
Honeywell’s goal was to derive a name that conveyed a smooth, sensitive, uninterrupted flow of air
–
This sensor’s high accuracy—
particularly its null accuracy and sensitivity at low flows—combined with its low pressure drop make “Zephyr” a fitting name
The Zephyr Name

•
Designed to measure mass flow of air and other non-corrosive gases•
Available in standard flow ranges•
Fully calibrated and temperature compensated with an on-board Application Specific Integrated Circuit (ASIC)
•
Provide a digital interface for reading airflow over the specified full scale flow span and temperature range
•
Thermally isolated heater and temperature sensing elements help provide a fast response to air or gas flow

7 Honeywell Zephyr™ Digital Airflow SensorsCopyright © 2010 Honeywell International Inc. All rights reserved.
Meet high accuracy specifications–
High 2.5% accuracy allows for a very precise airflow measurement, often ideal for demanding applications with high accuracy requirements
Customizable–
Allows the sensor to be designed to meet specific end-user needs
High sensitivity at very low flows–
Allows the application the ability to detect presence or absence
of airflow
High stability–
Reduces errors due to thermal effects and null shift to provide accurate readings over time, often eliminating need for system calibration after printed circuit board (PCB) mount and periodically over time
Low pressure drop–
Typically improves patient comfort in medical applications, and reduces noise and system wear in components such as motors and pumps
Saves design engineers time and money–
Linear output provides a more intuitive sensor signal than the raw output of basic airflow sensors, often eliminating the need to linearize the output, which can help to reduce production/design costs and implementation time
Competitive Differentiators

8 Honeywell Zephyr™ Digital Airflow SensorsCopyright © 2010 Honeywell International Inc. All rights reserved.
(in addition to competitive differentiators)1.
Small–
Occupies less space on the PCB, allowing for an easier fit and potentially reducing production costs
–
PCB size may also be reduced, easing fit in space-constrained applications 2.
Flexible–
Low 3.3 Vdc voltage option and low power supply allow for battery-driven and other portable applications
3.
Full calibration and temperature compensation–
Typically allows customers to remove additional signal conditioning components from the PCB, reducing PCB size and costs often associated with those components (e.g., acquisition, inventory, assembly)
4.
Fast response time –
Allows a customer's application to respond quickly to airflow change, important in medical (i.e., anesthesia) and industrial (i.e., fume hood) applications
5.
High 12-bit resolution–
Increases the ability to sense small airflow changes, allowing customers to more precisely control their application
Features and Benefits

9 Honeywell Zephyr™ Digital Airflow SensorsCopyright © 2010 Honeywell International Inc. All rights reserved.
6.
Bidirectional flow sensing capability–
Eliminates the need for two airflow sensors, helping customers reduce production costs and implementation time
7.
Insensitivity to mounting orientation–
Allows customers to position the sensor in the most optimal point in the system, eliminating concern for positional effects
8.
Insensitivity to altitude –
Eliminates customer-implemented altitude adjustments in the system, easing integration and reducing production costs by not having to purchase additional sensors for altitude adjustments
9.
RoHS-compliant materials –
Meets Directive 2002/95/EC
