Abstract

A gage/differential pressure transducer assembly having enhanced output capabilities, comprising a first pressure port adapted to communicate a first pressure to a first sensor, the first sensor comprising a first Wheatstone bridge adapted to output a first signal indicative of the first pressure, wherein the first pressure is a main pressure; and a second pressure port adapted to communicate a second pressure to a second sensor, the second sensor comprising a second Wheatstone bridge adapted to output a second signal indicative of the second pressure, wherein the second pressure is a reference pressure; and an output port connected to the first Wheatstone bridge and the second Wheatstone bridge for outputting a third signal representative of the difference between the first and second pressures.
