Abstract: Disclosed is a pressure measuring device, whose pressure sensor is protected against thermomechanical stresses, comprising a carrier, a support body arranged on the carrier, a pressure sensor arranged on the support body, a first joint including a joint material connecting the support body with the pressure sensor, and a second joint including a joint material connecting the support body with the carrier. The support body has on a face opposite the pressure sensor a first groove configured such that the first groove surrounds a joint area of the support body. The joint area of the support body and a footprint of the first joint are essentially equally large and significantly less than a base area of the pressure sensor opposite the first joint.

Abstract: Disclosed is an easily manufacturable pressure measuring system comprising a support, especially a support of metal, especially stainless steel, a pedestal connected with the support, and a pressure sensor mounted on a free end of the pedestal, in the case of which the pressure sensor is protected against thermomechanical stresses. The pressure measuring system is distinguished by features including that the pedestal includes a base arranged on the support, the pedestal includes a projection extending from the base toward the pressure sensor and comprising the free end of the pedestal, the base has a footprint, which is larger than a footprint of the projection, and the projection has a footprint, which is smaller than a footprint of the pressure sensor mounted thereon.

Abstract: A pressure measuring device comprises a carrier, a base which is connected to the carrier, and a pressure sensor which is mounted on the base, wherein a bottom base area of the pressure sensor is greater than a top base area of the base, the pressure sensor being protected against thermomechanical stresses by an end of the base, which is facing away from the pressure sensor, the end being adhesively bonded into a recess in the support by an adhesive bond.

Abstract: The invention describes a pressure measuring device having a carrier (1), a base (3) which is connected to the carrier (1), and a pressure sensor (5) which is mounted on the base (3) and of which the base area is greater than a base area of the base (5), the pressure sensor (5) being protected against thermomechanical stresses by an end, which is averted from the pressure sensor (5), of the base (3) being adhesively bonded into a recess (17) in the support (1) by means of an adhesive bond (19, 23, 25).

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.
