Abstract:
1. A pressure sensor comprising: a substrate which has conductor tracks for contact-connecting electrical components; a measuring element configured to convert a mechanical measurement variable into an electrical signal; a signal converter configured to process electrical signals from the measuring element; a first diaphragm which, together with the substrate, forms a first closed cavity that contains an inert filling medium; and a second diaphragm, wherein the substrate and the second diaphragm form a second closed cavity that contains an inert filling medium, the first closed cavity and the second closed cavity being arranged on an opposite side of the substrate; wherein at least one side of the measuring element, which comprises an active surface, has direct contact with the filling medium in the first closed cavity, and wherein the signal converter is arranged on the substrate and comprises an unhoused integrated circuit.
