Abstract: The present disclosure relates to a piston diaphragm seal for transmitting a pressure of a medium to a pressure-measuring sensor a base body having a recess and a bore which is connected to the recess. The recess and the bore can be filled with a pressure transfer medium. A piston is arranged in the recess and can be moved within a predetermined region in the recess. A surface of the piston facing the medium can be loaded with the pressure of the medium, wherein the piston is separated by at least two sealing elements from the medium and the pressure transfer medium. A cavity is arranged in the piston between the at least two sealing elements. An attachment region is provided for connecting the piston diaphragm seal to the pressure-measuring sensor. A monitoring unit is designed to determine and/or monitor entry of medium and/or pressure transfer medium into the cavity.

Abstract: A field device for processing and automation technology includes a first and a second component that can each be mechanically connected at a joining surface by means of a joining point. Two metal surface layers are each applied at least to the joining surface of the first component and the joining surface of the second component. The metal of the surface layers is different from the metal of the first and/or the metal of the second component. A joining material is applied between the respective joining surfaces of the two components, wherein the joining material includes particles at least partially consisting of a metal that corresponds with the metal of the surface layers The joining of the two components occurs at a joining temperature below 300° C.

Abstract: The present disclosure relates to a method for producing a pressure transmitter system, comprising the steps: providing a protective hose, a capillary tube and a pressure transmitter, which consists of a membrane support body and a filling adapter body that has a filling closure; arranging the capillary tube and a capillary interface of the capillary adapter relative to one another; integrally welding the capillary tube to the capillary adapter; and placing the protective hose onto a protective hose mounting of said capillary adapter.

Abstract: The present disclosure includes a method for manufacturing a pressure transmitter system, comprising steps as follows: providing a capillary adapter and a pressure transmitter, which has at least one diaphragm platform and an isolating diaphragm, which is connected along at least one edge gas-tightly with the diaphragm platform to form a pressure chamber between the isolating diaphragm and the diaphragm platform; welding the capillary adapter to the pressure transmitter; arranging the capillary tube and a capillary tube interface of the capillary adapter relative to one another; welding the capillary tube to the capillary adapter; and plugging a protective hose onto a protective hose seat of the capillary adapter.
