摘要： In a differential pressure sensor, the measurement value is corrected with the help of the nominal pressure NP. In this way, influences on the measurement value because of deformations of the body of the differential pressure sensor and change in the material stiffness of the membrane are decreased.

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 for measuring a pressure includes a pressure chamber; and a deformation body, which can be exposed to a medium under pressure, and which, additionally, at least partially bounds the pressure chamber and seals such pressure-tightly from the medium; wherein the walls of the sensor chamber have a hydrophobic coating, which was applied by gas and/or vapor phase deposition. The hydrophobic coating preferably includes a silane. Especially suited are silanes having one or more hydrophobic groups R and one or more anchoring groups X. Especially preferred are: R—Si—X3, R1R2—Si—X2, R1R2R3—Si—X. The hydrophobic group R is preferably an alkyl, perfluoroalkyl, phenyl or perflurorophenyl group. The anchoring group X is preferably an —OH (silanol), —X (halide, e.g. —Cl), —OR (ester, e.g. —OCH3), —NH2 (amine), or —SH (Mercaptosilane). Additionally, aliphatic or cyclic silazanes —Si—NH—Si—, e.g. hexamethyldisilazane, can be used. Likewise suitable are compounds of the type Ry—Me—Xz, with Me=e.g. Zr, Ti.

摘要： A chamber in the interior of a housing communicates with the environment of the housing by means of a gas esxchange path, wherein a filter element with a hydrophobic and/or hydrophobicized, nanoporous material is placed in the gas exchange path. The chamber serves, e.g. to accomodate electronic circuitry, or it is chamed as a reference pressure chamber of a relative pressure sensor. The relative pressure sensor according to the present invention for capturing a measured pressure with respect to a reference pressure comprises a reference pressure path 23 which extends between a surface which can be exposed to the reference pressure and an opening in a reference pressure chamber 22, a filter element 30 which is arranged in the reference pressure path comprising a hydrophobic or hydrophobicized, nanoporous material. The filter element allows pressure compensation on account of its permeability to N2 and O2, while water molecules are selectively blocked. The nanoporous material preferably comprises an inorganic material, in particular Al2O3, TiO2 or SiO2. The nanoporous material is preferably hydrophobic and/or can be impregnated with a hydrophobic layer, preferably a silane, in order to optimize the hydrophobic properties.

摘要： In this flush-diaphragm relative pressure sensor (1), the reference air reaches its current dew point before getting into the interior of the housing. The sensor has a capacitive, resistive, or piezoelectric sensing element (2) with a diaphragm (21) an external surface of which comes into direct contact with a medium under pressure. A housing (7) has an interior space (71) and a front portion (72) open across the interior space in the vicinity of which the diaphragm closes the interior space such that the front portion projects beyond the diaphragm. Further, the housing has a bore (721) extending through the front portion from an outer side thereof to the interior space for guiding the reference air. The bore is closed from the outer side with an open-pore, highly heat-conducting and hydrophobic filter (8), so that the filter and the diaphragm are at the same or nearly the same temperature. The filter can be made of a sintered metal, e.g. high-grade steel or bronze, or of a metallic sponge, e.g. titanium or zirconium.
