Ceramic pressure measuring cell and process for their preparation

A method of manufacturing a pressure-measuring cell 1, which has a ceramic base body 2 and a ceramic measuring diaphragm 3, wherein the measuring membrane by means of an active braze 4 pressure-tight manner to the basic body is joined, said method comprising: providing the base body 2 and the measuring diaphragm 3 and the active braze 4 ; Positioning the active brazing material, between the base body and the measuring membrane; Melting of the active brazing material by irradiating the active braze means of a laser 10, wherein the irradiation of the active brazing material is carried out by the measuring membrane; and solidifying the active brazing material by cooling.
