摘要： The invention relates to a method for data exchange between an operating and monitoring program (BA) and a field device (10, 20, 30), connected to the internet by means of a field bus adapter (5). The operating and application program (BA) accesses a serial interface (8), connected to an internet interface (13). A data exchange between the operating and monitoring program (BA) via the internet is thus possible without significant program changes.

摘要： The invention relates to a device for determining and/or monitoring the level of a filled substance (2) in a container (3), comprising a transceiver (9, 10), which generates and receives high-frequency measurement signals and an evaluation/control unit (11), which determines the level of the filled substance (2) in the container (3), using the run-duration of the high-frequency measurement signals. According to the invention, high frequency measurement signals are guided along a conductive element (6). The signals are coupled and decoupled using a coupling unit (8). The device is fixed to the container by means of a fixing part (5) mounted above the maximum level of the substance to be measured and/or monitored. A funnel-shaped element (7) is located in the upper region of the conductive element (6) in such a way that the lower opening surface (15) of said funnel that is oriented towards the surface (4) of the filled substance (2) lies approximately on the plane of the fixing part (5).

摘要： The invention relates to a pressure transmitter for transmitting the pressure prevailing in a first medium to a second medium. Said device comprises a pressure chamber (4) located in a base body (1), which is separated from the first medium by a separating membrane (2), wherein pressure can be transmitted by the second medium to a pressure measuring cell. An early warning detector is provided in order to timely identify an impending breakdown of the separating membrane. Said detector comprises a sensor chamber (6) having an opening that faces the first medium and a sensor (7) which monitors one characteristic of the medium contained in the sensor chamber. The detector further comprises a barrier facing the medium, which closes the hole in a pressure sealed manner. When said barrier comes into contact with the first medium under the same conditions as the separating membrane (2), it is more likely to break down than the separating membrane, thereby enabling fluidic connection between the sensor chamber (6) and the first medium. The barrier is preferably embodied as a sacrificial membrane (5) that is thinner than the separating membrane. In case of corrosive destruction of the membranes it is then to be expected that the sacrificial membrane (5) is more likely to be destroyed than the separating membrane (2).

摘要： The invention relates to a pressure measuring appliance which ensures that when the pressure transmission device is loaded, the liquid thereof, which is compressed by deviating the separation membrane into the supply line leading to the pressure measuring cell, can flow without interruption even when the separation membrane is positioned on the membrane bed, and without the position of the separation membrane on the membrane bed permanently impairing the elasticity of the separation membrane. To this end, the pressure measuring appliance comprises at least one pressure measuring cell (52) and at least one pressure transmission device (54, 56) having a pressure transmission base body (14), a separation membrane (16) which is fixed to said base body, a pressure transmission liquid (26) which fills the pressure transmission device (54, 56) and is used to transmit a process pressure from the separation membrane (16) to the pressure measuring cell (52), at least one supply line (66, 68) for supplying the liquid (26) of the pressure transmission device to the pressure measuring cell (52), a membrane bed (40) which is provided in the pressure transmission base body (14) and which faces the separation membrane (16), said separation membrane (16) resting on the membrane bed in the event of overload, a discontinuously formed surface (42) of the membrane bed (40), facing the separation membrane (16), and an eccentric confluence of the supply line (66) of the pressure transmission liquid (26) into an intermediate chamber formed by the separation membrane (16) and the membrane bed (40).

摘要： The invention relates to a pressure measuring cell comprising a base body (1, 23, 25), a membrane (5, 27) that is connected to the base body (1, 23, 25), thus forming a measuring chamber (3, 29, 31). During operation, the membrane is subjected to a deflection which is dependent on a pressure (p, p1-p2) that is to be measured. The cell also comprises a membrane bed, formed by a surface of the base body (1, 23, 25) that faces the membrane, at least one electrode (7, 33, 67) being mounted on said bed. Said electrode, together with a counter-electrode (9, 35, 69) that is mounted on the membrane (5, 27), forms a capacitor, whose capacitance represents a measurement for the deflection of the membrane (5, 27). The measuring cell is characterised in that the electrode (7, 33, 67) is electrically connected through the base body (1, 23, 25) and that the measuring chamber (3, 29, 31) has a smooth surface in the contact zone, said surface having a contact pin (13, 59, 73) that is guided in a bore (11, 57, 71) through the base body (1, 23, 25). The electrode (7, 33, 67) is electrically connected by means of said pin for measuring the capacitance and the pin is soldered into the bore (11, 57, 71) on the membrane side, using a solder (19, 57, 75). The contact pin (13, 59, 73), the solder (19, 57, 75) and the membrane bed form a smooth surface.
