Abstract:
Pressure-measurement device comprisinga pressure sensor (1) for measuring the pressure of liquid or gaseous media that has a base body (10), at one end of which measuring diaphragm (11) is located which is coupled to base body (10) by way of a first diffusion-tight joint (13); a diaphragm seal (2) that subjects measuring diaphragm (11) to a pressure to be measured by way of a pressure-transfer medium; wherein the pressure sensor (1) has a connection part (12) of a ceramic material which is coupled, on the diaphragm side, by way of a second diffusion-tight joint (14) to measuring diaphragm (11), and on the diaphragm seal side by way of a third diffusion-tight joint (24) to diaphragm seal (2).
