Abstract
In a particular embodiment, a process transmitter includes a corrosion resistive housing including a flange portion, where the corrosion resistive housing is formed from a first material. The process transmitter also includes an outer ring formed from a second material. The outer ring has an inner diameter and is brazed to the flange portion. The process transmitter further includes a deformable diaphragm formed from a third material, the deformable diaphragm is welded to the outer ring at a weld seam between the diaphragm and the outer ring adjacent to the inner diameter to form a fluid seal.
