Abstract

A pressure measuring device includes a ceramic pressure sensor and a process connection, the pressure sensor including a measuring membrane. The pressure measuring device further includes a carrier made of titanium and having a free-standing tubular carrier region running parallel to the surface normal onto the measuring membrane and having an end region adjacent the process connection connected to the process connection and an end region opposite the process connection to which the pressure sensor is fastened by a jointing that connects an outer edge of a front face of the pressure sensor to the end region of the carrier opposite the process connection and carries the pressure sensor.
