A fluid pressure sense element, such as a piezoresistive sense element () is disposed in one of the passageway openings and flexible metal diaphragms () are mounted on the respective diaphragm mounting surfaces of the module facing a common direction. A lower housing () having first and second port connections for the respective diaphragms is disposed on the lower surface of the module.
