Embodiment Construction

[0109] The technical solution of the present invention will be further described in detail through the following examples in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

[0110] figure 1 with figure 2 is a perspective view of a molded body 10 according to an embodiment of the present invention. Figures 3 to 6 is based on figure 1 with figure 2 A further illustration of the molded body 10 of the embodiment. Other examples of the molded body 10 are shown in Figures 7 to 13 as well as Figures 14 to 34 .

[0111] Figures 1 to 34 The molded body 10 shown is particularly suitable for use as a pressure sensor for measuring fluid pressure. The molded body 10 is advantageously a sensor body, in particular for a pressure sensor.

[0112] from Figures 1 to 34 As can be seen in the figure, the molded body 10 has a membrane 12 and a support portion 14 supporting the membrane. in accordance with Figures ...

Abstract

The invention relates to a shaped article, particularly for a pressure sensor, comprising a membrane and a support section supporting the membrane, at least parts of the membrane being produced from a ceramic material by additive manufacturing, particularly 3D screen printing, and the greatest possible distance between two points on the outer periphery of the membrane (12) being less than 20 mm.

Description

technical field [0001] The invention relates to a molded body, in particular a molded body for a pressure sensor, a pressure sensor comprising the molded body, and a method for producing the molded body. Background technique [0002] So-called ceramic or metallic pressure sensors can be used to measure the pressure of gaseous or liquid media. Ceramic pressure sensors with a ceramic sensor body containing a diaphragm are particularly suitable for measuring the pressure of aggressive media. [0003] However, the manufacture of ceramic pressure sensors requires a relatively high effort. For example, ceramic sensor bodies produced by pressing often require complex post-processing steps. This is because the pressing process used can only produce relatively thick and uneven layers. The corresponding membrane of the sensor body must therefore be mechanically reworked after pressing, for example by grinding or polishing, in order on the one hand to produce a sufficiently thin mem...
