The brake booster pressure sensor measures the relative pressure in the vacuum booster. In operation, the transducer senses the difference between the applied pressure and the atmospheric pressure via strain-sensitive piezo-resistors which are implanted in the silicon MEMS die membrane. Changes in resistance are converted into an output signal.
