AWM3150V Air Flow Sensor

GENERAL INFORMATION :

AWM3000 Series Microbridge Mass Airflow Sensors operate on the theory that airflow directed across the surface of a sensing element causes heat transfer. Output voltage varies in proportion to the mass of air or other gas flowing through a given sensor's inlet and outlet ports. Current sink/source. Maximum current ratings are 10 mA sinking and 20 mA sourcing, governed by an LM224 operational amplifier in the final stage of the instrumentation amplifier.

MEDIA CONTAMINATION :

Media flowing through the sensor should be free of condensing moisture and particulate contaminants. An inexpensive 5 micron filter upstream of the sensing element substantially reduces the risk of damage due to contaminants.

CLEANING:

Cover the ends of the ports when cleaning. Certain solvents may attack the epoxy used to seal the chip tubes to the ceramic substrate.

SOL DERING INSTRUCTIONS:

Please note: sensor should be securely attached to pr inted circuit boar d before soldering. Hand soldering: Use temperature controlled s S t m. Use Type R flux r oldering iron with 3,2 mm (1/8 in.) diameter tip. et temperature at 400 °C [750 °F]. Hold tip on erminal for 5 seconds maximu osin core solder and hand cle [4 an after soldering. Wave soldering: Set solder temperature at 250 °C 80 °F) maximum. Run belt at minimum of 1.54 m [5 ft] per minute. Cover tube ends when cleaning.
