摘要： A pressure-measuring cell having a base and a diaphragm positioned on the base is deformed by a pressure being measured. A temperature-measuring sensor is positioned between the diaphragm and the base preferably embedded in a material layer that seals a compartment. The diaphragm is preferably made of a ceramic and the material layer is preferably made of a glass.

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.

摘要： The invention pertains to a pressure sensor for a pressure measuring transducer which contains a base body (3), and a pressure-sensitive measuring membrane (7). The membrane is located on the base body (3) and can be subjected to a measurable pressure. The first chamber (10) is arranged between the base body (3) and the measuring membrane (7) in order to protect the measuring membrane (7) if the pressure to be measured exceeds an upper pressure limit. A second chamber (11) is provided to protect the measuring membrane (7) if the pressure to be measured falls short of a lower pressure limit. The second chamber (11) is arranged between the measuring membrane (7) and a contact plate (5) The contact plate is situated on the side of the measuring membrane (7) opposite the base body (3). A bore (6) is provided for subjecting the measuring membrane (7) to pressure.
