PRESSURE SENSOR WITH ACTIVE BRAZING

摘要

The invention relates to a pressure sensor with two bodies which are connected together by active brazing (7) produced by active brazing an active hard solder, in particular a measurement membrane (1), especially a ceramic measurement membrane (1), said measurement membrane being elastically deformable by applying pressure and being subjected to a pressure (p), and a base body (3), in particular a ceramic base body (3), which are connected by active brazing (7) connecting an outer edge of the measurement membrane (1), including a pressure chamber (5), to an outer edge of a front side of the base body (3) facing the measurement membrane (1). The measurement properties of the pressure sensor were improved in that the active brazing (7) has a thermal expansion coefficient which is dependent on the measurements of the active brazing (7) and the materials of the body, and is adapted to a thermal expansion coefficient of at least one body, in particular the measurement membrane (1).
