AWM730B5

Airflow Sensors AWM700 Series, Compensated/Amplified Datasheet Airflow Sensors The AWM700 Series, Compensated/Amplified Airflow Sensors provide in-line flow measurement with a specially designed bypass flow housing. These sensors measure flow as high as 300 standard liters per minute (SLPM) while inducing a typical pressure drop of 1 inH2O. The AWM700 has a high flow range capability in a small package, as well as a 6 ms response time. These sensors require a 10 Vdc supply, but consume only 60 mW of power. The compact plastic package withstands overpressures of 1720 mbar | 172 kPa | 25 psi without compromising performance. The snap-in AMP-compatible connector provides reliable connection. 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 and AWM730B5 were developed primarily for the medical ventilation market and meet the high performance requirements of many medical and analytical instrumentation applications. Key Features and Benefits • • • Potential Applications Flow tubes for ranges up to 300 SLPM: Provides low MedICAl pressure drop in the customer’s application • Oxygen concentrators and conservers Highly stable null and full scale: Does not require • Respirators and ventilators recalibration in most applications • Nebulizers Compact package design: Occupies less space in the • Continuous positive airway pressure (CPAP) customer’s enclosure, potentially reducing production costs; • Anesthesia machines enclosure size may also be reduced for easier fit into space• • • constrained applications INDUSTRIAL Low hysteresis and repeatability errors (less than • Mass flow controllers 0.35% of reading): Provides better system accuracy • Telecommunication systems Enhanced response flow time of 6 ms: Captures full flow • Environmental climate controls event • Fuel cell controls Low power consumption: Allows for use in portable • Process gas control welding equipment and lasers devices and battery-powered applications HIGHly STABle • COMPACT PACKAGE • LOW HYSTERESIS 2 sensing.honeywell.com AWM700 Series, Compensated/Amplified Table 1.
