摘要： A capacitive pressure measuring cell, including a ceramic platform and a ceramic measuring membrane, which are connected pressure tightly along a joint to form a reference pressure chamber between them. The measuring membrane has a first electrode facing the platform, and the platform has at least a second electrode facing the measuring membrane. The capacitance between the first and second electrodes depends on the difference between a pressure externally acting on the measuring membrane and a pressure reigning in the reference pressure chamber, wherein the joint has a thickness d, which defines an equilibrium distance between the measuring membrane and the front side of the platform. On the front side of the platform, a support layer is arranged, which comprises an inorganic insulator, wherein the support layer has a thickness of at least 0.2, and wherein the second electrode is arranged on the support layer.

摘要： A pressure sensor includes: a measuring cell having a base plate and a measuring membrane connected along its edge with the base plate, and means for generating an electrical quantity dependent on deformation of the measuring membrane; a circuit for registering the electrical quantity; and a capsule having a capsule body and a sealing element, with which the capsule is hermetically sealed along a joint. The capsule encloses the circuit, in order to protect such from influences of moisture; and the joint of the capsule is mechanically decoupled from the base plate. The mechanical decoupling of the joint means, for example, that at least the axial support of the pressure measuring cell in a housing is not allowed to be transferred through the joint. Despite arranging of the capsule on the base plate, pressure-related and temperature-related distortions of the base plate are not permitted to have any effects on the joint of the capsule.
