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.
