Abstract: A differential pressure sensor comprises a measuring diaphragm made of an electrically conductive material, two electrically insulating mating bodies, and at least one capacitive transducer. The measuring diaphragm is connected to the mating bodies in a pressure-tight manner with the formation of a measuring chamber in each case along a circumferential edge. The mating bodies each have a diaphragm bed which is concave in the center, wherein the mating bodies each have a pressure channel which extends through the mating body into the measuring chamber. The capacitive transducer has at least one mating body electrode which is formed by a metallic coating of the surface of the mating body in the region of the diaphragm bed and with which contact can be made by a metallic coating of the wall of the pressure channel.
