Airflow Sensors

line Guide

Go with the flow of engineering leadership. All airflow sensors

operate on heat transfer — flow and differential pressure.

But Honeywell Sensing and Control (S&C) offers advanced

chip design, manufacturing techniques and microstructure

technology, allowing our microbridge to be notably faster, smaller

and more sensitive. Our silicon chip design is created from a thin-

film, thermally isolated bridge structure, containing both heater

oR DiGiTAl AiRFlow SEnSoRS

HAF Series-High Accuracy.

Features: i = competitive differentiator

i High accuracy • Full calibration and

temperature compensation

i Customizable i High sensitivity at very

low flows i High stability i Low pressure

i Linear output • Fast response time

• High 11-bit (analog) or 12-bit (digital)

resolution • Low 3.3 Vdc operating

voltage • Analog or ASIC-based I

output • Bidirectional flow • Insensitive to

mounting orientation and altitude • Small

size • RoHS compliant

Benefits: High ±2.5% accuracy allows

for very precise airflow measurement,

often ideal for demanding applications

with high accuracy requirements. 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).

Customizable for specific end-user needs.

High sensitivity at very low flows allows a

customer’s application 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 the need for

system calibration after PCB mount and

periodically over 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. 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.

Fast response time allows a customer’s

application to respond quickly to airflow

change, important in critical medical

(i.e., anesthesia) and industrial (i.e., fume

hood) applications. High 11-bit (analog)

or 12-bit (digital) 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.

Analog output provides an interface for

and temperature sensing elements. This provides rapid response

to the air or gas flow and amount and direction, delivering

a proportional output voltage. Amplified versions provide

an enhanced output signal and less external circuitry, while

unamplified versions allow additional external circuit options.

What’s more, a variety of port styles provides greater application

flexibility.

reading airflow over the specified full

scale flow span and temperature. ASIC-

based I

eases integration to microprocessors or

microcontrollers, reducing PCB complexity

and component count. Bidirectional flow

sensing capability eliminates need for

two airflow sensors, helping to reduce

production costs and implementation

time. Insensitivity to mounting orientation

allows customer to position sensor in most

optimal point in the system, eliminating

concern for positional effects. 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. 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.

Potential medical applications include

anesthesia delivery machines, ventricular

assisted devices (heart pumps),

hospital diagnostics (spectrometry, gas

chromatography), nebulizers, oxygen
