Abstract
A differential capacitive pressure sensor of an embodiment of the present invention has first and second diaphragms positioned on opposing sides of a single substrate. Each diaphragm of the pressure transducer is configured to be exposed to a transient fluid, with the first and second pressure transducers being arranged with their respective deflection surfaces directed outwardly from each other. The differential capacitive pressure sensor may be configured to output representations of differential and common mode pressure of the transient fluids, where a representation of a common mode is cancelled in generating the representation of the differential pressure. The transient fluids may be the same fluid at different locations within a flow path. The diaphragms may be constructed from a ceramic material to be able to withstand exposure to corrosive or caustic fluids.
