The specially designed housing precisely directs and controls the airflow across the microstructure sensing element. The AWM40000 Series mass flow sensor family is based on proven microbridge technology and includes both amplified signal conditioned devices and unamplified sensor only devices. When using unamplified devices (AWM42150VH and AWM42300V), the heater control circuit and the sensing bridge supply circuit are both required for operation per specification. These two circuits are NOT on board the sensor and must be supplied in the application. A differential amplifier circuitry may be useful in providing output gain and/or introducing voltage offsets to the sensor output. The amplified devices (AWM43300V and AWM43600V) can be used to increase output gain and introduce voltage offsets. The differential instrumentation amplifier circuitry, heater control circuitry and sensing bridge supply circuitry are all provided onboard the amplified sensors.
