ABSTRACT:
A method of manufacturing a pressure sensor is provided whereby the pressure sensor includes a joint, a diaphragm, and an adapter disposed between the joint and the diaphragm. The adapter includes an axis portion and a flange projecting in a radial direction from the axis portion. The axis portion is disposed such that one end does not interfere with the joint and the other end is welded to the diaphragm. The diaphragm is welded to the adapter and the welded portion the welded portion is positioned on an inner side of an end face of the joint. The joint is caulked to a peripheral edge of the flange of the adapter.
