    Abstract: Sensor systems and methods are disclosed, which generally incorporate isolation between the sensor's electronics and the sensed media. The sensor's electronic circuit can incorporate one or more application specific integrated circuit (ASIC) that processes and outputs the signal for both absolute and differential measurements. Such a sensor can be adapted for use in exhaust gas re-circulation (EGR) systems utilized with automotive gasoline engines. Such a sensor can also be utilized for measuring differential pressure across diesel particular filters and/or applications in which differential pressure is required for system control and/or monitoring purposes. The absolute pressure sensor disclosed herein can therefore sense the exhaust pressure on automotive engines and other mechanical and/or electromechanical devices and machines.
