Pressure measurement unit in a pressure measurement system

摘要

Pressure measurement unit in a pressure measurement system 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). In 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).
