A resin producing method is a method of producing a resin with which an insulating structure formed on an outer peripheral portion of a conductor is impregnated, the method including: a filler mixing step of mixing a nanofiller at a ratio of 15 wt % or more with an epoxy resin to form a mixture; a shear mixing step of causing the mixture to be subjected to shear mixing; a diluent mixing step of mixing a reactive diluent that reduces a viscosity of the epoxy resin, with the mixture after the shear mixing step; and a curing agent mixing step of mixing an acid anhydride curing agent with the mixture after the diluent mixing step.

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.
