Abstract
A pressure sensor, comprising: a substrate having a measuring membrane, and an electrically conductive cover layer, which has electrical contact elements and is electrically isolated from the substrate by an insulating layer. The cover layer is divided in such a manner that two independent measurements of the respective resistance between two contact elements are possible in two regions electrically isolated from one another. The regions of the cover layer serve to shield external electromagnetic influences from the sensor elements of the measuring membrane, to detect damage to the measuring membrane, as well as for determining exact temperature.
