Abstract
A method and media-isolated absolute pressure sensor apparatus includes a first sensor () to measure a pressure difference between an isolated media (P) and a second media (Pa). A second sensor () measures an absolute (relative to vacuum) pressure of the second media (Pa). Each sensor () has its own offset and slope response. An equalizer () matches the slopes of the sensors (), wherein a summing circuit () can add the substantially same slope outputs to provide an output signal () indicative of an absolute pressure measurement of the isolated media (P). Offset and temperature compensation of each sensor can also be provided.
