Pressure and flow rate measuring cell

A pressure measuring cell comprising:

• a pipe piece through which a fluid flows having a resiliently deflectable diaphragm to which a pressure to be measured is applied arranged in a cross-section of the pipe;
• and
• a pipe-shaped carrier part having an internal diameter which is greater than an external diameter of the pipe piece and having a wall with a central circular opening arranged in a cross-section of the pipe-shaped carrier part, into which the pipe piece shortened to a thickness of the wall is inserted, the pipe-shaped carrier part projecting beyond the pipe piece in an axial direction on both sides;
• wherein the resiliently deflectable diaphragm and the pipe piece and are formed in one piece from a single material and are connected to one another via a solid-state joint;
• and
• wherein at least one sensor which records a deflection of the resiliently deflectable diaphragm are arranged one of (i) in a region of the solid-state joint on an outer side of the pipe piece and (ii) such that said at least one sensor is accessible from said outer side of the pipe piece.
