Pressure-measurment device |
摘要 |
The present invention pertains to a pressure-measurement device with a pressure sensor (1) for measuring the pressure of liquid or gaseous media and with a diaphragm seal (2) that subjects measuring diaphragm (11) of pressure sensor (1) to a pressure to be measured. Pressure sensor (1) has a connection part (12) made of a ceramic material which is connected to measuring diaphragm (11) on the diaphragm side via a joint (14) that is diffusion-tight towards the exterior, and is connected diffusion-tightly to diaphragm seal (2) 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 (1). The operational mode of the pressure transducer remains functional over a long time, and particularly at high temperatures.
