Honeywell Airflow Sensors AWM90000 Series

Airflow Sensors

AWM90000 Series microbridge mass airflow sensors are available in two versions,

mass flow and differential pressure. The AWM92100V has a flow range of ±200

SCCM with a pressure drop of only 0.49 mbar | 49 Pa | 0.007 psi, typically.

The AWM92200V is a differential pressure version that has a range of ±2 inH2O.

The AWM90000 Series sensors have a 1 ms response time, operate with a supply

voltage from 8.0 Vdc to 15.0 Vdc, while consuming only 50 mW of power.

The compact plastic package will withstand a maximum overpressure of 1720

mbar | 72 kPa | 25 psi without compromising performance. The sensor is well

suited for use in portable devices and battery powered applications.

The AWM90000 Series provides customers with a combination of time-proven

reliability, repeatable flow sensing, and the ability to customize the sensor

functions to meet their specific application needs.

Key Features and Benefits

• Bi-directional sensing capability: Allows use in applications where bidirectional

flow is present

• Highly stable null and full-scale: Does not require recalibration in most applications

• Low pressure drop: Provides improved system performance

• Compact package design: Occupies less space in the customer’s enclosure,

potentially reducing production costs; enclosure size may also be reduced for easier

fit into space constrained applications

• Low hysteresis and repeatability errors (less than 0.35% of reading): Provides

improved overall system accuracy

• Fast response time (1 ms typical): Captures full flow event

• Low power consumption (50 mW max,): Allows for use inportable devices and

battery-powered applications Potential Applications MedICAL

• Continuous Positive Airway Pressure (CPAP) equipment

• Sleep apnea monitors

• Oxygen conservers

• Oxygen concentrators

• Nebulizers

• Spirometers

INdUSTRIAL

• Variable Air Volume (VAV) damper control

• Clogged filter detection

• Fuel to air ratio sensing

• Leak detection equipment
