  • Field device interface seal and electrical insulation
    Patent number: 10816428
    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.
