Patent ID: 7360428

Claim:
A pressure measuring cell, having: a base body; a membrane, connected to said base body, forming a measuring chamber, which in operation executes a deflection that is dependent on a pressure to be measured; a membrane bed, to which said membrane conforms in the event of an overload, said membrane bed being formed by a surface, oriented toward said membrane, of said base body, onto which bed at least one electrode is applied, which together with a counter-electrode applied to said membrane forms a capacitor, whose capacitance is a measure for the deflection of said membrane; and a contact pin, passed through a bore through said base body, by way of which pin said at least one electrode is electrically connected for measuring the capacitance, and which toward said membrane bed is soldered into said bore with a solder wherein: said contact pin, said solder, and said membrane bed form a smooth surface.
