A differential pressure sensor may provide a common mode corrected differential pressure reading. The differential pressure sensor may include two pressure sensing diaphragms. The pressure sensor may be configured so that the first diaphragm measures the differential pressure between two sections of a fluid. The pressure sensor may also be configured so that the second diaphragm measures the common mode error experienced by the die at the time the differential pressure is read by the first diaphragm. Electrical connectors may be configured so that the differential pressure outputs a common mode error corrected differential pressure reading based on the readings of the first and second diaphragm.
