Abstract: A field device assembly includes an industrial process field device, a flange and a sealing and electrically insulating system. The field device includes a pressure sensor and a housing containing the active component. The housing includes a base having a base interface, which includes a first base process opening. The flange is attached to the base of the housing and includes a coplanar interface having a first flange process opening. The sealing and electrically insulating system includes a gasket that includes a dielectric material. A first process opening in the gasket is aligned with the first base process opening and the first flange process opening. A first surface of the gasket engages the base interface, and a second surface of the gasket that is opposite the first surface engages the coplanar interface. The gasket electrically insulates the housing of the field device from the flange.

Abstract: An industrial process field device includes a pressure sensor, and a housing containing the pressure sensor. The housing includes a base having a base interface and a first base process opening. A flange is attached to the base and includes a flange interface having a first flange process opening. A pressure at the first flange process opening is communicated to the pressure sensor through the first base process opening. A first gasket process opening of a gasket is aligned with the first base process opening and the first flange process opening. A first surface of the gasket engages the base interface, and a second surface of the gasket engages the flange interface. A dielectric insulation system includes at least one dielectric layer that insulates the housing from electrical currents conducted through the flange. Each dielectric layer includes a layer of ceramic material, an anodized layer, or a plastic overmold.

Abstract: A process variable transmitter is provided. The process variable transmitter includes a process variable sensor, and an electronics board having circuitry electrically coupled to the process variable sensor. The process variable transmitter also includes a shroud that holds the electronics board, and at least one stop feature to provide vibration damping. A method of manufacturing a process variable transmitter is provided. The method includes providing a process variable sensor. The method also includes providing an electronics board having circuitry configured to electrically couple to the process variable sensor. The method further includes forming a shroud to hold the electronics board, and forming at least one stop feature to support the electronics board when the electronics board is in the shroud.
