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 ( ) is disposed over the O-ring on a first portion ( ) of a two portion connector ( ) and retained by a second connector portion ( ). Protrusions ( ) formed on the tubular housing ( ) pass through cut-outs in the second connector portion to place a load on the loading washer. To facilitate assembly, the connector is attachable to the support member in one embodiment by legs of an EMC shield ( ), with the shield coupled to the connector by wedging tabs ( ) and in another embodiment by direct engagement of legs of the connector. In one embodiment a shroud ( ) is removably received on the connector to protect elongated terminals extending therefrom. One embodiment is provided with an enhanced environmental seal including a resilient grommet ( ) retained by a snap cap ( ).
