An oil-gas separation membrane combines a gas permeable yet oil and temperature resistant bulk polymer membrane such as poly(tetrafluoroethylene) and poly(tetrafluoroethylene-co-hexafluoropropylene); a porous metal support such as sintered metal frit disk made with stainless steel, bronze or nickel; and a highly gas permeable adhesive that firmly bonds the bulk polymer membrane and the metal frit surface together. The adhesive is either a homogenous polymer that has desirable gas permeability, or a coalescent porous polymer particulate network. A gas sensor employing the oil-gas separation membrane for detecting and monitoring fault gases of oil-filled electrical equipment requires no mechanical wearing or moving parts such as pumps and valves, and the gas sensor is operated normally under various temperature and pressure conditions.
