ABSTRACT:
A fluid differential pressure transmitter assembly includes a pressure sensor housing having a spacer within the housing to minimize the internal fill fluid used to conduct fluid pressure from a fluid inlet port to a pressure sensor located within the housing in the form of a pressure responsive diaphragm. Input pressures are applied to respective sides of the diaphragm to produce an electrical signal output representative of the differential pressure from piezoresistive elements deposited on the diaphragm. The sensor is electrically connected by flexible wires to electrically conductive paths supported on an end surface of the spacer. The conductive paths are, in turn, electrically connected to electrode wires at electrically conductive support junctions between the spacer and the electrode wires. However, the spacer is supported on the electrode wires at the support junctions in a free floating arrangement without any other physical contact to either adjacent elements within the housing or the interior wall of the housing. Thus, physical changes to the spacer such as those occasioned by temperature changes are not transmitted to the fluid seals. The electrode wires are arranged to pass through fluid-tight seals in the transmitter housing to provide external electrical connections to the sensor while supporting the spacer within the housing.
