AWM43300V Air Flow Sensor Mass Medical Amplified Low Vacuum Control
The small size and thermal isolation of the microbridge mass airflow sensor are responsible for the extremely fast response and high sensitivity to flows. Dual Wheatstone bridges control airflow measurement–one provides closed loop heater control, the other contains the dual sensing elements.
The heater circuit minimizes shift due to ambient temperature
changes by providing an output proportional to mass flow. The
circuit keeps the heater
temperature at a constant differential (160°C) above ambient air
temperature which is sensed by a heat-sunk resistor on the chip.
The ratiometric voltage output of the device corresponds to the
differential voltage across the Wheatstone bridge circuit.
