摘要:
The invention relates to the field of multilayer ceramics and relates to ceramic pressure sensors, such as can be used, for example, for industrial process control. The object of the invention is to disclose ceramic pressure sensors that are mounted in a largely mechanically stress-free manner and have a long service life, and the production of which is more effective and more cost-effective. The object is attained with ceramic pressure sensors, comprising a support of tapes, wherein the tape(s) embody at least one cavity that is covered with at least one ceramic pressure membrane tape or in which a ceramic pressure membrane tape covering the cavity is located, and wherein the tape(s) have at least one supply line for the pressure connection to the cavity, and the tape composite is sintered. The object is further attained with a method for production, in which at least one tape is structured for producing a cavity, at least one pressure membrane tape is positioned on the cavity for covering, and subsequently the tape composite is sintered.

摘要:
The present invention relates to a channel structure for a bioreactor, biochemical reactor, chemical reactor or a reformer comprising a plurality of individual layers stacked on one another and having a respective plurality of openings which pass completely through the respective individual layer and which are characterized in that at least two directly adjacent individual layers each have at least one layer section whose openings are arranged in the form of a pattern respectively regular in two dimensions and in that at least two of the layer sections provided with such a pattern in this manner of directly adjacent individual layers overlap at least in part, wherein the openings of the two at least partly overlapping layer sections are rotated and/or offset with respect to one another in the overlap region.
摘要:
Sensor for determining the electrical conductivity of liquid media comprising a multilayer layered structure (1), with a carrier substrate with two wound (3b, 4b) magnetizable cores (3a, 4a) and a dielectric coating. The invention also comprises a method in which a greenbody for a magnetizable core with metallic windings is applied onto a dielectric ceramic base green film, and a second magnetizable core with metallic windings is applied and subsequently a coating is applied before or after the sintering. The invention further comprises a method in which magnetizable cores with metallic windings are applied onto a dielectric organic base plate or base film.
摘要:
A compound body comprises a steel base element on which is deposited a heater layer. The base element is made of a precipitation hardening steel. In the form of a manifold or material feed tube in a hot duct system, said base element comprises a round or convex surface receiving the heater layer. This heater layer is a compound layer having several strata and/or strata elements which are thick film pastes or sheets and in such form are consecutively deposited, dried and baked-on. The pre-compression generated in this process in the heater layer is increased in controlled manner by precipitation hardening the base element.
