Abstract: A field device for an industrial process includes a digital isolator which electrically divides the field device into a primary side for low voltage electronics from a secondary side. A device power supply located in the secondary side is configured to provide power to a process control device which monitors or controls a process variable of the industrial process. A latching relay located in the secondary side couples to the process control device and the device power supply and has a set input to responsively couple the device power supply to the process control device and a reset input which causes the latching relay to enter an electrically open state to thereby disconnect the device power supply from the process control device. A controller located in the primary side is configured to generate a switch signal. The digital isolator extends between the primary side and the secondary side and couples to the switch signal from the controller and provides a digital output on the secondary side in response to the switch signal. Edge triggered circuitry couples to the digital output of the digital isolator and provides a pulse output to the reset input of the latching relay in response the digital output of the digital isolator.

Abstract: A process fluid pressure transmitter includes a pressure sensor body containing a pressure sensor that has an electrical characteristic that changes in response to applied pressure. An isolation diaphragm is configured to be exposed to process fluid. A fill fluid fluidically couples the isolation diaphragm to the pressure sensor. A weld ring is welded to the isolation diaphragm at a first weld. A barrier metal is disposed on at least one surface of the isolation diaphragm such that the barrier metal extends over the first weld. The weld ring is welded to the pressure sensor body at a second weld that is spaced from the barrier metal.
