Abstract
Apparatus and associated methods relate to generating a signal indicative of a differential pressure using a first absolute pressure sensor and a second absolute pressure sensor, each having a positive relation transducer configured to generate an electrical signal that increases in response to increasing pressure and a negative relation transducer configured to generate an electrical signal that decreases in response to increasing pressure. The first and second positive relation transducers of the first and second absolute pressure sensors, respectively, are electrically connected as a first leg of a Wheatstone bridge at a first output node. The first and second negative relation transducers of the first and second absolute pressure sensors, respectively, are electrically connected as a second leg of a Wheatstone bridge at a second output node. Both positive and both negative relation transducers are connected to a first and a second bias node of the Wheatstone bridge, respectively.
