    [0001] The present invention relates to a measuring device with at least one housing and at least two electronic assemblies.
    [0002] For the realization of a large bandwidth of different measuring devices, taking into account the measuring principles and also the dimensions or classes of protection, etc., so-called modules or systems for building modular boxes are occasionally used. In this case, the measuring devices in question will be constructed in a similar way and are possibly assembled with interchangeable components. This on the one hand has the advantage of an appearance that has a uniform recognition value. On the other hand, production costs are thus reduced, in other words, they result in greater flexibility for the adaptation of measuring devices to specific requirements. To this end, measuring devices will generally be subdivided into individual components that can be reciprocally combined and that can also have a modular construction.
    [0003] In measuring devices, there is a possible separation between a unit of a sensor, in which a measurement principle is realized for the effective measurement of the magnitude of the process, and an electronic unit that serves to evaluate or process the gross value or the value measurement that is generated by the sensor. In this way, eventually the sensor may also have its own electronic components that are used for the measurement or for the bidirectional transformation of the gross values. Both the sensor unit and the electronic unit are commonly integrated in the respective housing, with the sensor housing possibly having an opening for direct contact with the product to be measured and the housing of the electronic unit, presenting at least one opening for the energy supply, that is, for the transmission of the measured values, for example, to an overlapping unit. In addition, the two housings are commonly so shaped that they can be joined together and that a transmission of energy or signal can also take place between the sensor unit and the electronics unit.
    [0004] In addition, the electronic unit can be subdivided into several modules that eventually are also interchangeable or can be combined with each other. Subdivisions are possible in this case in a central unit that serves for energy supply, for control, for measurement and for processing the signals from sensor units into output signals, in a coupling or converter unit that is used for coupling the device meter and possibly an indicator or control unit that serves to indicate the measured value, that is, for the localized control of the measuring device.
    [0005] Depending on the degree of modularization, different couplings for different bus systems can be combined with random indicator units and different types of sensors. A modular finish of the electronics unit is shown, for example, in the DE 10 2006 009 827 A1 or DE 10 2009 054 649 A1 specification or in the DE 197 82 057 B4 patent. The DE 101 26 654 A1 specification describes a housing of a measuring device with an indicator compartment and a separate coupling compartment for receiving an indicator module, ie coupling module. A similar construction is disclosed in the European patent EP 0 775 292 B1 with a housing that has two compartments separated by a wall with a passage. The electronic components of the compartments are contacted reciprocally by signal pins that are provided fused in the passage. In the utility model DE 203 14 618 U1 there is a strip of pins cast into a passage compartment between two partial compartments of the housing. Another configuration of the housing and the modular electronic components therein are mentioned in WO 2011/160949 A1. Plug contacts, inside a fused measuring device that are directly coupled to an electronic component and used for connection with other electronic elements, are revealed, for example, in the specification DE 102 33 296 A1.
    [0006] In many uses, specific safety of measuring devices is required. The type of ignition protection “specific safety” is based mainly on a limitation of the electrical energy within the electronics of the measuring device, that is, within its segments and the electrical energy of connection lines to a level below that level at which , in contact with an explosive atmosphere, an ignition may be produced. An essential requirement resulting from the relevant standards is the preservation of separation distances between conductive components. The separation distance is the shortest distance between two of these components. A differentiation will be made according to the type of product, through which the shortest distance path passes, so that there are different separating distances for air travel, distance in the molten part, distances due to fixed insulation, leakage distances in air or escape paths, resulting under a protective layer. In addition, the separation distances to be observed depend on the maximum stresses between the conductive components.
    [0007] Details for the configuration of modular electronic components and their housing for possible use in a modular housing for measuring devices, are also found in the technical state. Thus, the DE 10 2010 033 470 A1 specification describes a control field for measuring devices and the DE 41 09 475 A1 specification describes a rotating display. A rotating mechanical connection between the sensor and the electronics housing is revealed by the specification DE 10 2004 044 890 A1. An interchangeable connection between the sensor, through a kind of plug, with a fieldbus or alternatively with a programming device, can be seen from the specification DE 103 27 013 A1. Other details like the easy introduction of a cable, inside a housing (for example, DE 10 2007 036 484 B3 patent), the production of a carbide thread inside an aluminum housing (for example, US patent 3,462. 539), or the application of coupling wires to a device with ceramic or glass gloves (for example, the utility model DE 20 2010 007 043 U), the fixing of electronic components using conical oblique planes in the housing (for example , the DE 10 2005 024 259 A1 descriptive report) or special devices on the outside of the housing for the anchor bolts (eg DE 10 2010 003 743 A1 descriptive report) can also be found in the state of the art and can contribute to the conformation of measuring devices and their housing.
    [0008] The object of the invention lies in proposing a measuring device, whose electronics are of modular constitution and that allows a simple adaptation for the specific production.
    [0009] The task presented in accordance with the invention is solved initially, and in an essential way in the measuring device addressed here, by the fact that at least one shielded contact element is provided. The contact element is formed separately from the electronic assemblies and housings, being integrated between two electronic assemblies. In addition, the contact element has at least one electronic transfer element to generate an electrical connection between the two electronic assemblies.
    [0010] In the state of the art it is known that electronic assemblies are found in chambers of a housing separated by a wall and the electronic assemblies are reciprocally contacted by transferring elements such as, for example, contact pins that are integrated in a passage of the wall where are fused. That is, a contact element of this type is almost part of the housing wall. In addition, it is known that different electronic assemblies have corresponding transfer elements and that for explosion protection, the entire electronic unit is fused. In the meter apparatus according to the invention, however, a separate contact element is provided as a specific component that is specially encapsulated - that is, it is itself and specifically encapsulated - and does not need to be encapsulated inside the housing as it occurs in the state of technical.
    [0011] A ready-made contact element that can be used allows, in addition to simplified use, also the easiest adaptation to the housings and versions used of the electronic assemblies. Therefore, the distance between the electronic assemblies can be easily regulated by the height of the respective contact element used between them. As the contact element is already encapsulated and does not require an encapsulation in the housing, in the measuring device according to the invention, defective components can also be replaced more easily because in a simpler case, only the plug-in connection between the electronic set and a contact element. It can also be produced relatively simple and differentiated arrangements of several transferring elements that eventually also have more complex structures, without, for example, support being required inside the housing before casting, as occurs in the state of the art.
    [0012] Furthermore, in this way an angular arrangement of the electronic assembly can also be realized, the contact element having a corresponding and adjusted angle. The contact of more than two electronic sets can also be carried out, with the contact element having several transfer elements at different spatial angles. As the contact element is already separated and encapsulated, you can clearly simplify, as part of a modular system, the combination of different electronic assemblies, that is, housings. A measuring device of this kind according to the invention is connected, for example, with different sensors that are used, for example, to measure the flow of the flow, to measure the level of filling, to measure the pH value and to the measurement of oxygen content and which are provided, for example, as a Corioles measuring device, as a MID measuring device, or as a radar fill level measuring device.
    [0013] According to one modality, it is provided that the transferring element is a contact pin. Preferably, several transfer elements are provided, all or partially formed as contact pins. Through contact pins of this type, the connection between the electronic assemblies is easy to be achieved, provided that the appropriate bushings are provided there. In one embodiment, the contact element has contact pins on both sides, facing the electronic assemblies, that is, transfixing contact pins are provided. Alternatively, the contact element has contact pins on one side and the other side features bushings. Random combinations with other transfer elements, such as plugs or cables, and / or vitrified are also possible within an external wall of the contact element. This encapsulation, that is, the glazing is used especially for the regulation of the minimum distances necessary for the type of protection against ignition between the current conductors, that is, contact elements. In one embodiment, several transfer elements are provided, all of which are fused and / or glazed within the outer wall of the contact element. The outer wall as part of the outer housing of the contact element may at least partially consist of noble steel or plastic. In a variant, the contact element is specially shaped as a plug or a stopper. The basic cross section is especially preferably circular, however, there is no restriction on this shape.
    [0014] In another modality, the cross section of the contact element is asymmetrical, so that the contact element can only be used in a defined orientation inside the housing, which automatically results in defined mounting and contact positions - also of the united electronic assemblies.
    [0015] Advantageously, the contact element and the two electronic assemblies are so shaped and reciprocally adjusted that the contact element and the two electronic assemblies are essentially interconnected, free from cracks. The dimensions of the electronic assemblies and their housings and the contact element are such that after a reciprocal union they are free from cracks.
    [0016] Preferably, this happens without additional sealing or casting elements. For increased safety, however, additional casting is possible, that is, additional sealing elements are possible around the contacting element, ie the two electronic assemblies. Less two chambers between which there is a passage. In this case, one of the two electronic assemblies and the contact element are arranged in each chamber in the passage. In this case, a contact element is already encapsulated in the measuring device according to the invention and is not formed - as in the state of the art - only by casting, for example, contact pins that cross a passage of this type. In one embodiment, the contact element is integrated with precise adjustment in the passage.
    [0017] In other modalities, the separation between the two electronic sets will be reinforced, that is, between the two chambers. In this case, it is envisaged in a modality that the contact element is fused in the passage, in addition to its encapsulation. In an alternative or complementary manner, the passage between at least one electronic assembly and the contact element is provided. Additionally, also in a complementary or alternative way, between at least one electronic unit and the contact element and / or between the element of contact and passage, at least one seal assembly is arranged - especially an O-ring. Alternatively, the entire internal compartment of the housing may also be fused.
    [0018] In one modality it is especially addressed that the measuring device in use, for example, as part of a process automation, is sometimes exposed to intense mechanical stresses. If a measuring device is integrated, for example, in a container - a silo or a tank - of a product with the sensor - the filling of the container or a mixing mechanism in the container can result in vibrations of the measuring device and, therefore, also when requesting electronic components, that is, contacts on the measuring device. Similar occurrences are valid when the measuring device is mounted, for example, in a tube for measuring the flow of the passage. In order to reduce the effects of these vibrations on the electronic components, the following conformation is foreseen, which, however, is also independent of the above mentioned species of the conformation element conformation, but likewise, it forms a very good combination in order to a measuring device, with the best possible optimization.
    [0019] The modality consists in that the accommodation has at least one electronic access for at least one of the two electronic sets. Therefore, the accommodation has an access or an opening, through which at least one electronic set can be reached, especially being able to be integrated. Through electronic access, a first longitudinal axis is especially extended. If, for example, the segment of the housing that is sequential to electronic access and that preferably covers an electronic set, is essentially cylindrical - for example, with a circular base face, then said first longitudinal axis will be the longitudinal axis of this cylindrical segment . Unloading the electronic access generally in an access plane, that is, if the accommodation is closed in an access plane of this type, then the first longitudinal axis will be especially normal to this access plane that extends in the center, through the electronic access. In addition, the housing has a sensor access for connecting a sensor. The sensor unit serves, in this case, for the effective measurement or control, for example, of a process quantity such as the filling level or flow of the flow, and generally provides raw values that arise from a dependence on a measurable quantity of the quantity process, used for measurement, that is, for control. For the coupling of a sensor of this type to the housing, a sensor access is provided, that is, an opening for the sensor. In this case, the sensor access flows into a coupling plane. As in many employing coupling of the measuring device in a container or in a pipe, etc., it occurs through a flange, a coupling plane of this kind can also be called a flange plane. Through the sensor access, a second longitudinal axis is especially extended. If this segment of the housing, which is sequential to the sensor access and which eventually also conforms to the contact with the sensor, is essentially cylindrical - possibly even having a circular basic face - then the second longitudinal axis will also be the longitudinal axis of this cylindrical part of the housing that serves for the passage to the sensor. The second longitudinal axis is in this case especially perpendicular to the coupling plane.
    [0020] In a special mode, the first longitudinal axis and the second longitudinal axis are perpendicularly superimposed, so that the housing is at least partially shaped in L or T. The angle between the first and the second longitudinal axes can, however, also have another value, so that eventually a Y-shape results, if at least a third segment is still provided for in the housing. In another exemplified modality, the access plane and the coupling plane are provided for diverging reciprocally, in relation to a parallel arrangement. The first and the second longitudinal axes especially cover an orientation plane that is especially perpendicular to the access and coupling plane.
    [0021] In addition, at least one electronic set has at least one platinum. Plates will generally be used to support the respective electronic components. In this case, the platinum is located essentially on a platinum plane. The stage is integrated in the housing in such a way that the stage of the stage is arranged at an angle to the orientation plane that differs from a 90 ° multiple. When, in the electronic access, it is a circular opening and serving the coupling plane as the base of an imaginary northern pole, then the platinum in this conformation is aligned neither in the north-south nor east-west direction. In a conformation, the platinum plane is arranged along the bisector of the quadrants, that is, in a northwest-southeast or northeast-southwest direction. In another conformation, moreover, the plane of the stage is arranged at an angle to the coupling plane, which also differs from an entire multiple of 90 °. Therefore, the platinum plane preferably in this mode is disposed neither perpendicularly to the coupling plane, nor in parallel with respect to this plane. In another embodiment, the platinum plane is preferably arranged at an angle of 45 °, relative to the coupling plane. With such an “oblique” arrangement of the platinum, relative to the coupling plane, the force acting on the vibrations on the platinum and its components will be reduced, especially by the vector division of forces acting on the platinum plane.
    [0022] In detail, there are several possibilities for conforming and measuring apparatus according to the invention. To this end, reference is made on the one hand to the claims subsequent to claim 1, on the other hand, the following description of examples of implementation, in connection with the drawing. The figures show:
    [0023] Figure 1 - a schematic layout, essentially basic, of a representation that presents a part of a measuring device, in section.
    [0024] Figure 2 - top view for the measuring device according to figure 1.
    [0025] Figure 3 - Spatial presentation of a measuring device housing.
    [0026] Figure 4 - spatial presentation of a measuring device, and
    [0027] Figure 5 - Spatial presentation of another variant of a measuring device housing.
    [0028] Figure 1 shows a section through a part of a measuring device 1, according to the invention, schematically presented, and figure 2 shows a top view of this device. Figure 3 offers a spatial view for a housing 2 of a measuring device 1. Another variant of a housing 2 as part of a measuring device 1 is shown spatially by figure 4.
    [0029] Figure 1 shows a part of the measuring device 1 of the invention, covering housing 2, in which there is an electronic unit. In order to obtain a complete measuring device 1, with functional capacity, in the lower area of the housing 2, only a corresponding sensor unit will have to be coupled, within which the respective measurement principle employed will be transformed, in order to obtain it from the process quantity to be measured, (for example, flow rate or fill level), preferably an electrical measurement quantity. In housing 2 there are two electronic assemblies 3, 4 which, in the transformation shown in the invention, are arranged sequentially. In the larger electronic set 4, a conductive structure can be recognized on the wall, whereby electronic set 4 can be inserted more easily and securely into housing 2 during assembly and, thus, incorrect assembly or damage can be avoided of individual components. Hence it is also part that the electronic set 4, that is, the internal wall of the housing 2 is conical shaped. The other electronic set 3 has, for example, several clamping contacts which are arranged in the direction of the internal wall of the housing 2 and which allow for its multiple and especially redundant conformation that, for example, an indicator or control unit can be applied and contacted with a selectable orientation.
    [0030] Between the two electronic assemblies 3, 4 there is the contact element 5 which is shielded and shaped specially separated from the two electronic assemblies 3, 4. The contact element 5 serves, in this case, for the electrical connection between the assemblies electronics 3, 4 and also for the separation of the two electronic assemblies 3, 4, for example, to ensure specific safety.
    [0031] For the connection, transfer elements 6 are provided, which are realized here as pins in both directions. The transferring elements 6 are fused or vitrified within the outer wall 7, which here consists of noble steel, this wall of the contacting element 5, and for the specific protection, care is taken regarding the necessary distances between the different transferring elements 6. In an alternative embodiment, the outer wall 7 consists of a plastic or a composite material. In the version shown here, the contact element 5 is shaped like a stopper.
    [0032] The internal compartment of the housing 2 is subdivided here into two chambers 8, 9, in which there is an electronic unit 3, 4. The two chambers 8, 9 are separated by a wall that presents a passage 10 that houses the element contact element 5. In the present case, the passage 10 and the contact element 5 are so shaped and reciprocally synchronized that the contact element 5 is integrated with precise adjustment in the passage 10.
    [0033] In the neck of the housing 2 that projects down here, the respective sensor unit will be specially arranged, being, for example, secured by a screw. By using, for example, a bayonet type lock, however, a variant can also be made, in which the sensor unit and the housing can be partially rotated or partially rotated in the opposite direction. The lower neck allows, for example, also the introduction of cables or, for example, flexible conductive plates that start from the sensor unit - not shown here, and that can be joined with electronic assemblies 3, 4.
    [0034] In an assembly of the measuring device 1 according to the invention, the electronic assemblies 3, 4 and the contact element 5 will be inserted in the housing 2 and inserted reciprocally. When, in this process, the contact element 5 and the respective electronic assembly 3, 4 are joined together without reciprocation, then due to the encapsulation of the contact element 5, no other casting is required as occurs in the state of the art. The plug connection is especially reversible so that, even in the assembled state, individual components can still be replaced.
    [0035] Figure 1 also makes it possible to recognize other threaded gloves 11 that are inserted, for example, pressed into housing 2. In this case, these gloves 11 are made of noble steel that can be screwed or pressed into an aluminum housing 2 or plastic.
    [0036] Figure 2 allows a view on the electronic access 12 in the measuring device 1. The first longitudinal axis of this segment extends in the case in the presented variant, being perpendicular within the drawing plane. The electronic set 4 that can be seen has several conductive plates or plates, of which one plate 17 is on a platinum plane 18. In this case, it can be recognized that the other plates are also on parallel planes platinum 18. In the lower neck of housing 2, a sensor access 14 is provided for connection and contacting with a sensor - not shown here. The end of the housing 2 ends in the case in a coupling plane 19, where the second longitudinal axis 15 of this segment of the housing 2 is perpendicular.
    [0037] The first longitudinal axis and the second longitudinal axis 15 comprise an orientation plane 16 which also extends perpendicularly to the drawn plane. As can be seen, the plane of the platinum 18 is inclined at an angle α = 45 ° in front of the orientation plane 16. In this case, however, other angles a are also realized, in other modalities not shown here. It is common for all variants that the angle α differs from an integer multiple of 90 °, that is, the plane of the platinum 18 is neither arranged in parallel with the orientation plane 16, nor perpendicular to this plane. The plate 17 is also arranged at an angle of 45 ° to the coupling plane 19. Also in this relative orientation of the plate 17 or the conductive plate, in relation to the coupling plane 19, other angles are possible which always lead to an oblique position of the platinum 17. This inclination towards the coupling plane 19, through which the measuring device 1 is usually mounted in a container or in a tube, will reduce the effects of vibrations on platinum 17, that is, its components, or component contacts.
    [0038] In the variant shown, it can also be recognized that housing 2 still has three other side accesses, for example, for cable connections.
    [0039] Figure 3 shows a housing 2, in which the first longitudinal axis 13 of the electronic access 12 and the second longitudinal axis 15 of the sensor access 14 are drawn. In the presented variant, the two longitudinal axes 13 and 15 form each other a right angle and therefore define an orientation plane that can be correspondingly considered as a symmetrical plane of accommodation 2, in relation to the two observed segments. The plate 17 indicated here, in relation to its position, is visibly tilted against the plane formed by the two longitudinal axes 13 and 14. Below the electronic access 12, it is still possible to recognize the deformity that allows a cover to be attached with a screw in the housing 2 and even mount a lead.
    [0040] The measuring device 1 of figure 4 consists of housing 2 and sensor 20. Both are interconnected, for example, through a screw. The sensor 20 shown in concrete form is just an example that other random types of sensors 20 can be coupled for the different measurement principles in a housing 2 of this nature. It is essential for the combination of the different groups of components that the segments in reciprocal contact are reciprocally synchronized so, for example, for the connection between the housing 2 and the sensor 20, one must look at corresponding neck geometries. If there is a connection between the housing 2 and the sensor 20 via a thread, then through a corresponding slope, that is, through a corresponding number of threads, the requirements of standards can also be met between the two units explosion protection, differentiated.
    [0041] In the variant shown, housing 2 is closed with a lid, through which an indicator and control element can be seen. For the control, for example, mechanical keys with a special laminate. Alternatively, however, a capacitive or inductive keyboard that reacts to the approach of a finger or pin may also be realized. In another variant, Hall sensors are provided in housing 2, which can be controlled via magnetic pins, through a closed lid and thus also meet the requirement for explosion protection. If contact pins are used between a display module and the underlying electronics, it is also simplified to fasten the display module and eventually the rotation of the indicator unit, in front of housing 2, can also be transformed in a simple way. For example, the number of contact pins is increased and the contact pins are shaped redundantly at different spatial angles. In this case, in the indicator unit, that is, in the corresponding electronic unit, pins or bushings can also be varied. Alternatively, there is compaction through cables, so that only the assembly of the indicator and control set should allow for a differentiated relative adjustment.
    [0042] In housing 2 of the measuring device 1 of figure 5, the first longitudinal axis 13 of the electronic access 12 and the second longitudinal axis 15 of the sensor access 14 coincide, because in this variant both accesses 12,14 are sequentially arranged in an aligned manner , and between the components of the measuring device 1, inside the housing 2, there is a connection as shown in figure 1. An electronic set is highlighted here in the drawing, separately, a platinum 17 for a better visualization of its orientation. the housing 2 has an electric coupling compartment 21 with a third longitudinal axis 22 which is essentially perpendicular to the first 13 or the second longitudinal axis 15. The third 22 and the first 13, that is, the second longitudinal axis 15 forms a plane in relation to which the platinum plane 17 is arranged at a different angle to an integer multiple of 90 °.
