Embodiment Construction

[0031] figure 1A schematic block diagram of a device 1 for determining pressure according to one embodiment of the invention is shown.

[0032] The device 1 has a housing 10 with a cavity 12 which has a mouth 13 which opens out from the cavity 12 to the outside of the housing 10 . The housing 10 also has a first sealing structure 14 . The device 1 also comprises a sensor device 20 with a second sealing structure 24 . The second sealing structure 24 cooperates with the first sealing structure 14 in such a way that the mouth 13 of the cavity 12 can be closed or is closed by the sensor device 20 by means of the first sealing structure 14 and the second sealing structure 24 .

[0033] The cavity is subjected to a pressure to be determined in that a fluid, which is charged with the pressure to be determined, is introduced into the cavity or has been introduced into the cavity, the sensor device 20 being designed to determine the Pressure to be determined.

[0034] The device 1 ...

Abstract

PROBLEM TO BE SOLVED: To provide a structure which is hard to be broken, by proving an automatic sealing property to a high-pressure sensor.SOLUTION: A pressure measuring device 100 has a casing 110 equipped with a hollow chamber 12 and a first seal structure portion, and a sensor device equipped with a second seal structure portion. The second seal structure portion is engaged with the first seal structure portion, and an opening portion 13 of the hollow chamber can be blocked by the sensor device. The sensor device is formed so as to measure pressure applied on the hollow chamber. The pressure measuring device further has a seal device. At least a part of the seal device is disposed in the hollow chamber, and by adding pressing force to the sensor device, the second seal structure portion is pressed on the first seal structure portion.SELECTED DRAWING: Figure 2

Description

technical field [0001] The invention relates to a device for determining pressure and to a method for producing the device for determining pressure. In particular, the invention relates to a pressure sensor, preferably a high-pressure sensor, which has a self-sealing construction and connection technology. A “high pressure sensor” is to be understood in particular as a sensor designed to determine a pressure above 2000 bar, preferably above 2500 bar, particularly preferably above 3000 bar, wherein the high pressure sensor is advantageously not damaged. 1 bar is equivalent to 100,000 pascals. Background technique [0002] In hydraulics and in many areas of process technology, pressure sensors, ie devices for determining pressure, especially pressures greater than 50 bar, play an important role. In particular in vehicle construction, such devices are used in various systems, for example in direct fuel injection and driving dynamics control. In general, so-called piezoresist...
