Abstract
A diaphragm type fluid pressure gauge comprises a case formed of an injection molded thermoplastic. The bottom wall of the case selectively defines a rear axial fluid connection or a radial fluid connection to a fluid chamber defined within the case. The fluid chamber is closed by a diaphragm which is clamped against an annular radial surface in the case by a thermoplastic ring which is melt-welded to the case. The other face of the ring provides a mounting for a movement mechanism for driving a pointer in response to axial displacement of the diaphragm.
