Features
  • Laser trimmed for improved sensor interchangeability
  • Flow sensing up to 1.0 SLPM
  • Low differential pressure sensing
Typical Applications
  • Damper control for heating, ventilation, and air conditioning systems
  • Gas analyzers
  • Low vacuum control
  • Process control
  • Medical respirators and ventilators
  • Oxygen concentrators
  • Leak detection equipment
  • Vent hoods
  • Anesthesia control
  • Gas metering
  • Gas chromatography
Description
Like the AWM2000 Series, the dual Wheatstone bridges control airflow measurement. The AWM3000 Series is amplified; therefore, it can be used to increase the gain and to introduce voltage offsets to the sensor output. The heater control circuit and the sensing bridge supply circuit are on board the package.

CAUTION
PRODUCT DAMAGE
AWM Series Microbridge Mass Airflow Sensors are not designed to sense liquid flow and will be damaged by liquid flow through the sensor.
Failure to comply with these instructions could result in product damage.
