Microbridge Mass Airflow Sensors are manufactured using silicon based technology.
The microstructure chip consists of a thin-film,
thermally isolated “bridge” structure containing a heater and
temperature sensing elements, all spanning an etched cavity.
Heater temperature is 160 Deg C above ambient temperature.
This is controlled on board the sensor.
Airflow sensors operate on the principles of heat transfer due to
Air flow across the bridge transfers heat to the sensing elements causing a change in resistance.
Output voltage varies in proportion to the flow of media through the package.
Specially designed housings precisely directs the airflow assisting in detection of flow rate as well as direction.
The AWM series of products is a natural extension of our existing Pressure Sensor product line.
