Adjustment of air mass flow sensor with tunable output stage

摘要

A desired output voltage of the output stage is determined corresp. to the measured input voltage. The measured input voltage is applied at the output stage, and the output stage is turned corresp. to the applied measured input voltage, for the prodn. of the desired output voltage. The step for the turning of the output stage includes the step of the adjustment of the resistances in the output stage. The step of the tuning of the desired output voltage includes: adjusting a low air flow, measuring an input and output voltage of the output stage with low air flow, adjusting a high air flow, and measuring the input and output voltage of the output stage with high air flow.
