ABSTRACT OF THE DISCLOSURE The present invention provides a pressure gauge comprising an aneroid capsule, in which the relative movement of opposing aneroid capsule walls is transformed into a capacitive quantity, a first condenser plate mounted inside the aneroid capsule on one of the opposing walls, a second condenser plate facing the first plate on the other opposing wall, said condenser plates defining a condenser having a capacitance proportional to the pressure, said one opposing wall being pierced by an insulated inlet assembly which fixes the first condenser plate thereon at the point where the amplitude of the movement thereof is substantially at its largest.
