Abstract: A port fitting is formed with a closed, pedestal end forming a diaphragm on which a strain gauge sensor is mounted. A support member is received on the pedestal end and is formed with a flat end wall having an aperture aligned with the sensor. A portion of a flexible circuit assembly is bonded to the flat end wall with a connector disposed over the support member. A tubular outer housing is fitted over the several components and its bottom portion is welded to the port fitting while its top portion places a selected load on an O-ring received about the connector as well as internal components of the transducer. In one embodiment, a loading washer (72a) is disposed over the O-ring on a first portion (70a) of a two portion connector (70) and retained by a second connector portion (70b). Protrusions (76a1) formed on the tubular housing (76) pass through cut-outs in the second connector portion to place a load on the loading washer.
