Original Honeywell AWM42300V, AWM43300V, AWM43300VH, AWM43600V, AWM43600V-2, AWM42150VH Flow Sensors Series
Honeywell AWM40000 Series Mass Airflow Sensors
These are MEMS micro‑bridge thermal mass gas flow sensors, for dry gas only, widely used in ventilators, oxygen concentrators, anesthesia machines, gas analyzers, leak detection, chromatographyHoneywell.
Suffix rule:
- 42xxx: Unamplified raw bridge output, need external heater & amplifier circuit
- 43xxx: On‑board amplified 0‑5 V analog output, direct MCU read
- ‑H: Ceramic flow tube (high common‑mode pressure 150 psi); no‑H = plastic manifold port (25 psi max)
- ‑2: Revised medical‑optimized varian
- awm40000 Series
