Abstract
A single pressure sensor is caused to provide a pressure measurement at two separate pressure regions through the use of a differential pressure switch whose switch over point occurs when the two regions are at a fixed pressure differential or offset. The sensor is connected to sense a first region with a sensor output signal being compared to a signal related to the count in a counter. Upon switch over the counter is actuated to make a signal equal to the sensor output signal. The counter signal, compensated for the offset, is related to the pressure at the second region.
