A field device has a housing providing EMC-protection. The housing includes a conductive housing core, which is surrounded on all sides by a non-conductive housing jacket secured thereon by force-interlocking, e.g. frictional interlocking, or by material bonding. At least one electrically conductive barrier is placed on and connected with an electrically conducting region of the housing core and divides the interior of the housing into at least two chambers with different degrees of EMC-protection. The barrier contains a passageway, with which at least a first electronic circuit and a second electronic circuit, which are located in different chambers, are contacted with one another. The circuits are contacted by spring contacts against regions of the housing core, which are led through the housing jacket into the interior, wherein transitions to a sensor&#x2014;or lid in the housing by means of screw thread&#x2014;and/or wiping contacts are so arranged that these kinds of components are electrically connected with the housing core and wherein seals of the transitions protect against environmental influences.

Field device for use in process automation

A field device for determining or monitoring a process variable in process automation. The field device includes: sensor, which works according to a defined measuring principle; and a control/evaluation unit, which conditions and evaluates measurement data delivered by the sensor along at least two equal valued measuring paths as a function of a safety standard required in a particular safety-critical application. The control/evaluation unit is embodied, at least partly, as a reconfigurable logic chip, with a plurality of partially dynamically reconfigurable, function modules. The control/evaluation unit so configures the function modules in the measuring paths as a function of the defined safety-critical application, that the field device is correspondingly designed to the required safety standard.

Field device for determining or monitoring a process variable in process automation

A method for safe data communication via WAN, LAN (e.g. Internet) between at least one external access unit and a field device, or a field bus adapter for determining or monitoring at least one physical or chemical process parameter. According to the method unauthorized accessing of a field device, or a field bus adapter, in the field is blocked in that the operator of the field device or the field bus adapter permits the external access unit to have targeted access to the field device, or the field bus adapter.

Method for securing the exchange of data between an external access unit and field device

An apparatus for determining and/or monitoring pressure. The apparatus comprises at least one pressure transducer, which transduces pressure into an electrical signal. The invention includes the features that at least one acoustic sensor is provided, that the acoustic sensor registers acoustic signals and transduces such into electrical signals, and that the acoustic sensor is mechanically and/or acoustically coupled with the pressure transducer.

Apparatus for determining and/or monitoring ( {A} ) pressure

An apparatus for determining and/or monitoring at least one process variable of a medium. The apparatus includes: at least one sensor unit for registering the process variable, wherein the sensor unit produces measurement signals; at least one electronics unit for controlling the sensor unit, wherein the electronics unit has at least one microprocessor; and at least one memory unit, which is associated with the sensor unit, and in which control data are storable. The control data specifically relate to the sensor unit and can be read out by the electronics unit. The microprocessor of the electronics unit is embodied in such a manner, that the microprocessor executes in an inactive state only basic functionalities, and that the microprocessor in an active state controls the sensor unit. The microprocessor transfers from the inactive state into the active state transfers by loading control data from the memory unit.

Apparatus for determining and/or monitoring a process variable

A method for testing an electronics unit, especially an electronics unit of an apparatus for ascertaining and/or monitoring a process variable, wherein the electronics unit has a plurality of electrical components. At least a part of the electrical components is grouped into at least one group, and this group is supplied with a query signal. A response signal is received from the group, and the response signal is evaluated. Furthermore, the invention relates to an apparatus for determining and/or monitoring a process variable.

Method for testing an electronics unit

A configurable field device for automation technology with a partially dynamically reconfigurable logic chip FPGA, in which function modules are dynamically configured during runtime, and to a method for operating the configurable field device.

Configurable field device for use in process automation systems

A device is provided for the detachable fastening of one or more instruments (1) at one or more locations and their electrical connection to a cable (5) having one or more wires, using at least one fastening element which is mounted at one of the locations, in which device each instrument (1) has a snap mounting (12) by means of which it can be locked onto the respective fastening element, in which the electrical connection of the respective instrument (1) is carried out while it is being locked on, in which a cable mounting (4) is arranged on the fastening element, which cable mounting has a profile (45) reproducing the line shape, into which the line (5) is inserted, and which has a guide element which, while the instrument (1) is being locked on, engages into an identically-shaped recess (13) on the instrument (1), and in which the connection of the respective instrument (1) to the wires of the line (5) while the respective snap mounting (12) is being locked onto the respective fastening element is carried out, according to a first solution variant, by penetration contacts (6) arranged on the respective instrument (1), or is carried out, according to a second solution variant, by penetration contacts (91) arranged in a cover (9) arranged between instrument (1) and cable mounting (4), said penetration contacts being electrically connected to plug contacts (92) which are arranged on the cover (9) and which, in turn, engage in plug connectors (15) arranged on the instrument (1) while the latter is being locked on.
