ABSTRACT:
A pressure to current transmitter has an internal fill fluid chamber separated from a process fluid by a diaphragm and backup plate. A fluid-tight seal is achieved between the backup plate and the wall of the fluid chamber by a continuous weld bead while the wall of the chamber is arranged on a flexible cantilever to accommodate differential thermal expansion between the backup plate and the chamber wall.
