Beschreibung
Zusammenfassung:	A pressure measuring device includes a ceramic pressure sensor including a ceramic measuring membrane and a sensor mounting configured to secure the pressure sensor such that a membrane region of the measuring membrane surrounded by a membrane edge is contactable with a medium having a pressure to be measured. The sensor mounting includes a titanium or titanium alloy mounting element including an opening through which the membrane region is contactable with the medium. The membrane edge is connected directly with the mounting element by a diffusion weld produced by a diffusion welding method.
