    摘要: A method for reducing the content of foreign molecules in gaseous or liquid form dissolved in a pressure transfer liquid of a pressure measuring transducer. A pressure receiving chamber is closed by an isolating diaphragm. A pressure measuring chamber is connected to the pressure receiving chamber, and a pressure sensor arranged in the pressure measuring chamber, in which the liquid serves to fill an inner space of the pressure measuring transducer formed by the pressure receiving chamber is provided. The pressure measuring chamber is connected therewith, and transfers an external pressure acting on the isolating diaphragm to the pressure sensor in measurement operation. The liquid is brought into contact with at least one adsorptive body, and foreign molecules dissolved in the liquid are bound to the adsorptive bodies by adsorption.

    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.

    摘要: A pressure measuring cell includes at least one ceramic measuring membrane body; and at least one ceramic platform, wherein the measuring membrane body is connected with the platform along an annular, peripheral joint. The joint is formed as a welded connection between the measuring membrane body and the platform, wherein the measuring membrane body has a pressure-dependently deformable measuring membrane. A pressure sensor includes a pressure measuring cell and a housing, wherein the pressure measuring cell is held by the housing, and wherein the pressure measuring cell closes a housing opening, through which the pressure measuring cell communicates with an environment of the housing. A seal is clamped between a sealing surface surrounding the opening of the housing and a sealing surface of the pressure measuring cell.
