Abstract: A differential pressure measuring cell comprises a measuring membrane; two opposing bodies; and one converter. The measuring membrane is arranged between the opposing bodies and is connected in a pressure-tight manner to the two opposing bodies, forming in each case one measuring chamber. The opposing bodies each have a pressure duct through which a pressure can be made to act upon the respective measuring chamber. The converter is provided in order to convert a deformation of the measuring membrane, which deformation is dependent upon a difference between the pressures, into an electrical signal; wherein the opposing bodies each have a chamber section oriented toward the measuring membrane and a rear wall section oriented away from the measuring membrane with, between these, a decoupling chamber. The chamber sections each have an equalizing duct between the measuring chamber and the decoupling chamber, wherein the decoupling chamber has a diameter that is at least as large as the diameter of the measuring chamber.
