Abstract: The present invention relates to a mounting assembly (21) for a pressure sensor (30) in a pressure transmitter (10). The mounting assembly (21) includes a header (58) having a cavity (32) opening to a first surface (103). The cavity (32) is defined by an inner endwall (164) and an inner sidewall (130). A support (120) is joined to the inner endwall (164) within the cavity on a first support end (150). A pedestal (102) has a first pedestal end (102A) supporting the pressure sensor (30) and a second pedestal end (102B) joined to a second support end (136). Aligning means (132) align the second pedestal end (102B) to the second support end (136) in order that a volume of the mounting assembly (21) is increased to thereby reduce a quantity of fill fluid needed in the sensor cavity (32).
