Pressure measurement unit mounted in encircling housing
First Claim
1. Pressure measurement unit in a pressure measurement system, with a housing section (8), which has an internal space (9) with an internal surface, and with a ceramic unit (1) which has a pressure diaphragm (2) and at least one external surface, whereinthe ceramic unit (1) is held in the housing section (8) in a press fit, resulting in radial holding stresses between the external surface of the ceramic unit (1) and the internal surface of the housing section (8), wherein the radial holding stresses are parallel to a plane of the pressure diaphragm.

Abstract
A pressure measurement unit in a pressure measurement system has a housing section (8) which has an internal space (9) with internal surfaces, and a ceramic unit (1) which has a pressure diaphragm (2) and at least one external surface, with the ceramic unit (1) held in the press fit in the housing section (8) and with radial holding stresses operating between the external surface of the ceramic unit (1) and the internal surfaces of the housing section (8). A method for manufacturing a corresponding pressure measurement unit with a housing section (8) and with a ceramic unit (1) which has a pressure diaphragm (2) and at least one external surface, with holding stresses built up between the housing section (8) and the ceramic unit (1), which hold the ceramic unit (1) in the internal space of the housing section (8).

- 12. Method for manufacturing a pressure measurement unit with a housing section (8), which has an internal space (9) with internal surfaces, and with a ceramic unit (1), which has a pressure diaphragm (2) and at least one external surface, comprising the step of building up radial holding stresses between the housing section (8) and the ceramic unit (1), which hold the ceramic unit (1) in the internal space (9) of the housing section (8), wherein the radial holding stresses are parallel to a plane of the pressure diaphragm.
