ARRANGEMENT OF A SENSOR ELEMENT ON A VACUUM-INSULATED CONTAINER SYSTEM, PARTICULARLY ON A CRYOTANK

摘要

The invention relates to an arrangement of a temperature sensor (6) on a vacuum-insulated container system, particularly for storing cryogenic hydrogen. The container system consists of an interior container (2) for storing a medium, a vacuum insulation layer (4) surrounding this interior container and an exterior container (1) retaining said vacuum, from which exterior container the interior container is suspended in bearing elements (3a, 3b) and in which exterior container an evacuation opening closed off by means of a closure stopper (5) is provided. The sensor system has a measuring probe (6a) arranged on the interior container and an electronics unit (6b) connected to the probe, the signals of which unit can be picked up outside the exterior container via an electrical contact. The electronics unit connected via a lead to the measuring probe is arranged on or outside the closure stopper through which this lead is run, in such a manner that the electronics unit can be replaced without breaking the vacuum insulation layer and said lead is run between the measuring probe and electronics unit through a bearing element.
