Introduction

The AWM90000 Series Microbridge Mass Airflow Sensors are available in both mass flow and differential pressure versions. The AWM92100V offers a flow range of ±200 SCCM with a typical pressure drop of only 0.49 mbar (49 Pa, 0.007 psi). The AWM92200V is the differential pressure version with a range of ±2 inH₂O. This sensor series features a 1 ms response time, an operating supply voltage of 8.0 Vdc to 15.0 Vdc, and a power consumption of only 50 mW. The compact plastic package withstands overpressure up to 1720 mbar (72 kPa, 25 psi) without affecting performance, making it ideal for portable and battery-powered applications. The series offers customers time-proven reliability, repeatable flow sensing, and the ability to customize sensor functionality to meet specific application requirements.

Features

• Bidirectional sensing capability: enables use in applications with bidirectional flow
• Highly stable zero and full-scale points: eliminates the need for recalibration in most applications
• Low pressure drop: improves system performance
• Compact package design: smaller footprint in customer housings, potentially reducing production costs; housing dimensions can also be reduced for easier integration in space-constrained applications
• Low hysteresis and repeatability error (less than 0.35% of reading): improves overall system accuracy
• Fast response time (typical 1 ms): captures complete flow events
• Low power consumption (50 mW max): enables use in portable and battery-powered applications

Applications

• Medical: continuous positive airway pressure (CPAP) equipment, sleep apnea monitors, oxygen conservers, oxygen concentrators, nebulizers
• Industrial: variable air volume (VAV) damper control, clogged filter detection, fuel-air ratio sensing, leak detection equipment
