EG Electronics | Honeywell AWM700 Airflow Sensor

Main Features

Flow tubes for ranges up to 300 SLPM: Provides low pressure drop in the customer’s application

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

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 spaceconstrained applications

Low hysteresis and repeatability errors (less than 0.35% of reading): Provides better system accuracy

Enhanced response flow time of 6 ms: Captures full flow event

Low power consumption: Allows for use in portable devices and battery-powered applications

Description

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 H2O, typically. The AWM700 has a high flow range capability in a small package.

The sensor 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 sensors provide a combination of time proven reliability, high accuracy, and precision operating characteristics for use in the medical ventilation market and medical and analytical instrumentation applications.

Its accuracy over life reduces the need for recalibration. AWM700 sensor circuitry performs amplification and temperature compensation.

AWM Series Microbridge Mass Airflow Sensors are not designed to sense liquid flow and will be damaged by liquid flow through the sensor.
