Abstract

The present invention pertains to a pressure-measurement device with a pressure sensor ( ) for measuring the pressure of liquid or gaseous media and with a diaphragm seal ( ) that subjects measuring diaphragm ( ) of pressure sensor ( ) to a pressure to be measured. Pressure sensor ( ) has a connection part ( ) made of a ceramic material which is connected to measuring diaphragm ( ) on the diaphragm side via a joint ( ) that is diffusion-tight towards the exterior, and is connected diffusion-tightly to diaphragm seal ( ) on the diaphragm seal side. In this way, it is assured that no gases or water vapor can enter the pressure-transfer medium via pressure sensor ( ). The operational mode of the pressure transducer remains functional over a long time, and particularly at high temperatures.
