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.

Each dielectric layer includes a layer of ceramic material, an anodized layer, or a plastic overmold, which improve a maximum working pressure of the field device.
