WARNING

PERSONAL INJURY

• DO NOT USE these

products as safety or

emergency stop devices or

in any other application

where failure of the product

could result in personal

injury.

Failure to comply with these

instructions could result in

death or serious injury.

AWM700 Series microbridge mass airflow sensors provide in-line flow

measurement with a specially designed bypass flow housing. The sensors

measure flow as high as 200 standard liters per minute (SLPM) while

inducing a pressure drop of 1 inch H

O, typically. The AWM700 has a high

flow range capability in a small package.

The AWM700 has a 6 millisecond response time, requires a 10 Vdc

supply, but consumes only 60 mW of power. The compact plastic package

withstands overpressures of 25 psi without compromising performance.

The snap-in AMP compatible connector provides reliable connection. The

sensor is also well suited for use in portable devices and battery-powered

applications.

The AWM700 Series provides a combination of time proven reliability,

high accuracy, and precision operating characteristics. This inherent

accuracy over life reduces need for recalibration. AWM700 sensor circuitry

performs amplification and temperature compensation.

The AWM720P1 200 LPM Mass Airflow Sensor, developed primarily for

the medical ventilation market, meets the high performance requirements

of many medical and analytical instrumentation applications.
