摘要： The invention relates to a pressure sensor (1) comprising a main body (2) and at least one measuring membrane (3), which is connected to the main body in a pressure-tight manner, forming a measuring chamber, by means of a first joint (4) comprising a first active hard solder, and a transducer (5, 6a, 6b) for converting a pressure-dependent deformation of the measuring membrane into an electric primary signal, and a primary signal path that extends from the transducer through at least one bore (8a, 8b) through the main body, wherein the primary signal path comprises at least one electrically conductive coating (7a, 7b) that extends along the wall of the bore (8a, 8b) without closing the bore. According to the invention the bore (8a, 8b) is closed by means of a second joint (10a, 10b) using a second active hard solder, wherein the second active hard solder closes the bore in a self-supporting manner and wherein the second active hard solder has a surface capable of being soft-soldered.
