The electronics unit connected to the measuring sensor via a line is arranged on the sealing plug or outside the sealing plug through which this line is passed in such a way that the electronics unit can be replaced without breaking the vacuum insulation layer, and it is the said line between the measuring sensor and the electronics unit passed through a bearing element.
Description
Die Erfindung betrifft eine Anordnung eines Sensorsystems, insbesondere eines Temperatursensors, an einem vakuumisolierten Behältersystem, insbesondere an einem Kryotank für die Speicherung von tiefkaltem Wasserstoff, wobei das Behältersystem aus einem Innenbehälter zur Speicherung eines Mediums, insbesondere von tiefkaltem Wasserstoff, ferner aus einer diesen Innenbehälter umgebenden Vakuum-Isolationsschicht und einem dieses Vakuum haltenden Außenbehälter besteht, an welchem der Innenbehälter in Lagerelementen aufgehängt ist und in welchem eine mittels eines Verschlussstopfens verschlossene Evakuierungsöffnung vorgesehen ist, und wobei das Sensorsystem einen am Innenbehälter angeordneten Messfühler sowie eine mit diesem verbundene Elektronikeinheit aufweist, deren Signale über einen elektrischen Kontakt außerhalb des Außenbehälters abgreifbar sind. Zum Stand der Technik wird beispielshalber auf die
In einem vakuumisolierten Behältersystem kann ein tiefkaltes Medium zumeist ausreichend gut gespeichert werden, wobei jedoch die Minimierung von Wärmebrücken zwischen einem das tiefkalte Medium beinhaltenden Innenbehälter und einem diesen unter Darstellung einer Vakuumisolationsschicht umgebenden Außenbehälter von immenser Wichtigkeit ist. Dabei sind geringe Wärmebrücken zwischen dem Innenbehälter und dem Außenbehälter unvermeidbar, denn es muss der Innenbehälter innerhalb des Außenbehälters gelagert sein und es muss eine Befüllung und Entleerung des Innenbehälters möglich sein. Weiterhin müssen üblicherweise Messwerte bspw. hinsichtlich Temperatur und/oder Druck des im Innenbehälter gespeicherten Mediums vom Innenbehälter durch die Vakuumisolationsschicht sowie durch den Auenbehälter hindurch nach „außen” übermittelt werden.In a vacuum-insulated container system, a cryogenic medium can usually be stored sufficiently well, but the minimization of thermal bridges between an inner container containing the cryogenic medium and an outer container surrounding it with a vacuum insulation layer is of immense importance. In this case, low thermal bridges between the inner container and the outer container unavoidable, because it must be stored inside the outer container within the outer container and it must be possible to fill and empty the inner container. Furthermore, measured values, for example, with regard to temperature and / or pressure of the medium stored in the inner container, usually have to be transmitted from the inner container through the vacuum insulation layer and through the outer container to the "outside".
Für die Ermittlung und Übermittlung der Temperatur ist in der eingangs zweitgenannten
Die in diesem bekannten Stand der Technik gezeigte Temperatur-Messanordnung ist jedoch relativ aufwändig, weshalb vorliegend eine Anordnung eines Sensorsystems, insbesondere Temperatursensors an einem vakuumisolierten Behältersystem aufgezeigt werden soll, aufgrund derer oder mit welcher ein Bestandteil des Sensorsystems bzw. Temperatursensors im Falle der üblichen Defekte soweit austauschbar ist, dass hierbei das Vakuum des Behältersystems nicht gebrochen werden muss (= Aufgabe der vorliegenden Erfindung).However, the temperature measuring arrangement shown in this known prior art is relatively complex, which is why an arrangement of a sensor system, in particular temperature sensor to be shown on a vacuum-insulated container system, due to which or with which a component of the sensor system or temperature sensor in the case of the usual defects if it is interchangeable that in this case the vacuum of the container system does not have to be broken (= object of the present invention).
Die Lösung dieser Aufgabe ist für eine Sensorsystem-Anordnung nach dem Oberbegriff des Anspruchs 1 dadurch gekennzeichnet, dass die mit dem Messfühler über eine Leitung verbundene Elektronikeinheit am Verschlussstopfen oder außerhalb des Verschlussstopfens, durch den diese Leitung hindurchgeführt ist, derart angeordnet ist, dass die Elektronikeinheit des Sensorsystems ohne Brechen der Vakuumisolationsschicht austauschbar ist, und dass die besagte Leitung zwischen dem Messfühler und der Elektronikeinheit durch ein Lagerelement hindurchgeführt ist. Vorteilhafte Weiterbildungen sind Inhalt der Unteransprüche.The solution to this problem is for a sensor system arrangement according to the preamble of claim 1, characterized in that the electronic unit connected to the sensor via a line on the plug or outside of the sealing plug, through which this line is passed, is arranged such that the electronic unit the sensor system is interchangeable without breaking the vacuum insulation layer, and that said line between the sensor and the electronic unit is passed through a bearing element. Advantageous developments are content of the dependent claims.
Es wurde erkannt, dass die häufigsten Defekte in Sensorsystemen bzw. Temperatursensoren nicht am eigentlichen Messfühler selbst, sondern an einer dessen Signale weiter bearbeitenden Elektronikeinheit, die auch als elektronische Auswerteeinheit bezeichnet werden kann, auftreten. Wenn somit am Temperatursensor ein Defekt auftritt, muss mit größerer Wahrscheinlich die besagte Elektronikeinheit und nicht der Messfühler als solcher ausgetauscht werden. Aufbauend auf dieser Erkenntnis ist nun bei einem erfindungsgemäßen Sensorsystem eine Trennung vorgesehen zwischen dem reinen bzw. eigentlichen Messfühler als solchem und einer mit diesem verbundenen Elektronikeinheit (des Sensorsystems). Letztere ist erfindungsgemäß außerhalb der Vakuumisolationsschicht angeordnet und kann daher im Falle eines Defekts ohne Brechen des Vakuums ausgetauscht werden. Um dabei keine zusätzliche Wärmebrücke zwischen dem Innenbehälter und dem Außenbehälter zu schaffen, ist eine Verbindungs-Leitung zwischen dem Messfühler und der genannten Elektronikeinheit durch eine bereits vorhandene Wärmebrücke, nämlich eine Lagereinheit für den Innenbehälter im Außenbehälter hindurch geführt, wobei der Vollständigkeit halber darauf hingewiesen sei, dass durch die besagte Leitung zwischen dem Messfühler und der zugehörigen Elektronikeinheit des Sensorsystems, bspw. Temperatursensors die Information über die vom Messfühler ermittelte Temperatur auf unterschiedliche Weise, d. h. nicht auf eine elektrische Übermittlung beschränkt, übertragen werden kann.It has been recognized that the most frequent defects in sensor systems or temperature sensors do not occur at the actual sensor itself, but at an electronics unit that further processes its signals, which can also be referred to as an electronic evaluation unit. Thus, if a defect occurs at the temperature sensor, it is more likely that the electronic unit is replaced, not the sensor itself. Based on this knowledge, a separation is now provided in a sensor system according to the invention between the pure or actual measuring sensor as such and an electronic unit (of the sensor system) connected thereto. The latter is according to the invention arranged outside the vacuum insulation layer and can therefore be replaced in the event of a defect without breaking the vacuum. In order to create no additional thermal bridge between the inner container and the outer container, a connection line between the sensor and the said electronic unit through an existing thermal bridge, namely a storage unit for the inner container in the outer container passed through, it being pointed out for the sake of completeness in that the information about the temperature determined by the sensor is emitted in different ways by the said line between the measuring sensor and the associated electronic unit of the sensor system, for example a temperature sensor. H. not limited to electrical transmission, can be transmitted.
Wenn die Leitung zwischen dem Messfühler und der Elektronikeinheit durch das ein Loslager bildendes Lagerelement hindurchgeführt ist, so ist gewährleistet, dass Längenänderungen des Innenbehälters aufgrund größerer Temperaturschwankungen keine nachteilige Auswirkung auf die Anordnung des Sensorsystems, d. h. auf dessen Messfühler bzw. auf dessen Funktion haben, indem der Messfühler identisch positioniert sicher am Innenbehälter verbleibt, auch wenn sich dessen Geometrie aufgrund von Temperaturänderungen geringfügig ändert. Auch im Hinblick auf Längenänderungen des Innenbehälters aufgrund größerer Temperaturschwankungen kann zur Gewährleistung einer sicheren Funktionsweise des Sensorsystems (bspw. Temperatursensors) zwischen dessen Messfühler und dem Verschlusstopfen ein Anpresselement vorgesehen sein, welches den an der Wand und vorzugsweise an einem Behälterverschluss des Innenbehälters anliegenden Messfühler gegen diese Wand oder diesen Behälterverschluss drückt. Im Falle eines Temperatursensors ist damit unter allen Umständen ein ausreichender Wärmeübergang zwischen der die Temperatur des im Innenbehälter befindlichen Mediums widerspiegelnden Wand des Innenbehälters und dem Messfühler sichergestellt.If the line between the sensor and the electronic unit is passed through the bearing element forming a floating bearing, so is ensures that changes in length of the inner container due to greater temperature fluctuations have no adverse effect on the arrangement of the sensor system, ie on the probe or on its function by the probe remains identically positioned securely on the inner container, even if its geometry changes slightly due to temperature changes. Also with regard to changes in the length of the inner container due to greater temperature fluctuations, a pressure element may be provided between its sensor and the closure plug to ensure safe operation of the sensor system (eg temperature sensor), which against the wall and preferably on a container closure of the inner container sensor against this Wall or this container closure presses. In the case of a temperature sensor, a sufficient heat transfer between the wall of the inner container reflecting the temperature of the medium located in the inner container and the measuring sensor is ensured under all circumstances.
