PMFc3000 (AWM3000 compatible)
|
|
The PMFc3000 series of Mass Air Flow Sensors offer pin compatible upgrade solutions to the popular AWM3000 series from Honeywell. Using the robust Posifa Thermal Flow Sensor Die, and incorporating the latest microcontroller technology, PMFc3000 offers drastically improved interchangeability (< 2% F.S.), temperature stability (< 3% F.S. from 0°C to +50°C), and resistance to adverse environmental factors such as dust particles and water vapor that have plagued the AWM3000.
