MASS AIRFLOW
AWM2000 Series
The AWM2000 Series microbridge mass airflow
sensor is a passive device comprised of two
Wheatstone bridges and has bidirectional sensing
capability. The heater control circuit is required for
operation per specifications. The sensing bridge
supply circuit is also required for operation per
specifications. These two circuits are not on board
the package and must be supplied in the
application. The differential amplifier is a useful
interface for the sensing bridge. It can be used to
introduce gain and to voltage offsets to the sensor
output.

Mass Airflow sensors contain a thin-film, thermally isolated bridge structure containing heater and
temperature sensing elements. The bridge structure provides a sensitive and fast response to the flow of
air or other gas over the chip.
State-of-the-art chip design and manufacturing techniques allow the microbridge to be remarkably
sensitive, fast, small. Used wherever airflow needs to be measured.

AWM3000 Series
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.

The microbridge mass airflow sensor operates on
the theory of heat transfer. Mass airflow is directed
across the surface of the sensing elements. Output
voltage varies in proportion to the mass air or
other gas flow through the inlet and outlet ports of
the package. The specially designed housing
precisely directs and controls the airflow across
the microstructure sensing element. Mechanical
design of the package allows it to be easily
mounted to printed circuit boards.
The microbridge mass airflow sensor has a unique
silicon chip based on advanced microstructure
technology. It consists of a thin-film, thermally
isolated bridge structure containing heater and
temperature sensing elements. The bridge
structure provides a sensitive and fast response to
the flow of air or other gas over the chip. Dual
sensing elements positioned on both sides of a
central heating element indicate flow direction as
well as flow rate. Laser trimmed thick film and thin
film resistors provide consistent interchangeability
from one device to the next.
