Abstract: In a data logger (1) it is provided to couple in a detachable fashion to one another an electronic housing part (7) which accommodates an electronic part (2) embodied with a sensor signal-processing device (4) and at least one measuring sensor (5), to a battery housing part (8) which accommodates a battery (6) for supplying the sensor signal-processing device (4), wherein in the coupled state an electrical connection between the battery (6) and the sensor signal-processing device (4) is established via contacts (12) and corresponding mating contacts (13), and in the uncoupled state it is disconnected, and wherein in the coupled state a seal (10) on the coupling (9) protects the contacts (12) and the mating contacts (13) with respect to the outside.

Abstract: A probe holder having an access element which can be fitted to an opening in a wall of a pipe is provided. The access element has at least a portion of a continuous access opening, which is constructed for inserting a rod-like measuring instrument into the opening, and having a retention element which is constructed to secure the probe holder to the wall of the pipe. An arresting element is arranged to be movable relative to the access element in an insertion direction of the access opening between a first position and a second position, wherein the arresting element cooperates with the retention element in such a manner that in the first position a state which fixes the securing is defined and in the second position a state which releases the securing is defined.

Abstract: A valve block includes at least a first connection and a second connection. Both connections are connected to each other inside the valve block to temporarily change flow paths in a coolant device and/or to fill the coolant device and/or empty the coolant device. The valve block may be made of a coolant and pressure-resistant plastic and may be manufactured by an injection molding method.

Abstract: A method and apparatus for setting a characteristic of a source hearing device on target hearing device are provided. A transformation database is created. A source hearing device including the setting of the source hearing device are identified, the characteristic of setting is to be set on the target hearing device. The setting which, according to the transformation database on the target hearing device, results in the characteristic corresponding to the characteristic of the identified source hearing device is recalled. The target hearing device is set using the recalled setting. Settings are stored in the transformation database during their creation, which have to be set to hearing devices of different types to be set in order to grant these hearing devices the characteristic of other identified hearing with identified settings.
