Vacuum Brake Booster Sensor
Pressure Sensors
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.
