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 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.

The sensor cell comprises a ceramic substrate (1) having a cylindrical surface (11), a major surfaces (12, 13). The major surface (12) includes a concave central area (121) merging, in the direction of and up to said cylindrical surface (11), into a convex surface (124) having a vertex line (125) and forming a planar ring surface (126) in its area. An electrode (122) is located in the concave area (121). An electrical connection (123) extends from electrode (122) through the substrate (1) to surface (13). A ceramic diaphragm (5) has a planar inner surface (51) on which an electrode (52) is located and which rests on the ring surface (126) of the substrate (1). The diaphragm (5) is joined to the substrate by an active brazing solder forming a circumferential wedge zone (91) in the area of the substrate between the ring surface (126) and the cylindrical surface (11). An electrical connection to the electrode (52) is made through the wedge zone (91). Respective differential pressure sensors can comprise a central substrate (2) and two outer diaphragms (61, 71) or a central diaphragm (8) and two outer substrates (3, 4).
