Description

[0001] The invention relates to a measuring coupling for Fulda systems for detecting system states present within the Fulda system, in particular a pressure or a temperature, with a base body and a measuring device arranged on the base body.

[0002] A variety of measuring couplings are known from the prior art. These are used to integrate measuring devices into fluid power systems, particularly for pressure, temperature, or flow monitoring. A common design features a central body designed as a dual adapter with a gas spring, which provides two opposing measuring ports for integration into a media line. These systems are frequently used in hydraulic or pneumatic applications where the measuring points are accessible via flexible hose lines.

[0003] A disadvantage of these known systems is the multitude of potential leak points, particularly in the area of ​​the measuring connections. Each measuring device typically comprises several sealing levels, namely the connection and / or transition between the coupling body and the central body, as well as the interface to the actual measuring unit and / or the line. Due to the small cross-sections and usually high operating pressures, even minor leaks have a direct adverse impact on functionality and operational reliability.

[0004] A further disadvantage arises from the type of connection using flexible hoses, which are used to facilitate installation and accessibility of the measuring units. However, these hose lines are susceptible to vibrations, which occur particularly in mobile machinery, pump applications, or fast-acting hydraulic control blocks. The vibrations can lead to relative movement at the plug-in or screw connections, which can result in premature material fatigue on the one hand and loosening of the connecting elements on the other. These disadvantages are exacerbated, particularly in the case of multiple measuring devices, such as two opposing measuring couplings, due to the connection on both sides of hoses with different lengths, bend radii, and mass distributions.

[0005] The invention is therefore based on the object of overcoming the aforementioned disadvantages and providing a measuring coupling in which a connection between the measuring coupling and the measuring device is optimized and leakage points are minimized.

[0006] This problem is solved by the combination of features according to claim 1.

[0007] The basic idea of ​​the invention is that the measuring coupling is designed with a T-screw connection, in which two opposing connection elements are provided for fluid-carrying lines and only one lateral measuring connection for a measuring device. Preferably, at least one connection element has a vibration-proof device for reducing vibration between the line and the measuring coupling, in particular the connection element. Furthermore, the reduction to just one measuring connection reduces the number of potential leak points.

[0008] According to the invention, a measuring coupling for Fulda systems for detecting system states within the Fulda system, in particular a pressure or temperature, is proposed, comprising a base body and a measuring connection for a measuring device arranged on the base body. The base body has two opposing connection elements for a respective fluid-carrying line. Furthermore, the measuring connection for the measuring device is formed on the side of the base body and as a screw-on connection, such that a T-shaped screw-on connection is formed.

[0013] In a further advantageous variant, the invention provides that the vibration protection device has at least one O-ring arranged on one of the connecting elements.

[0014] The measuring coupling according to the invention is designed in a variant such that the vibration protection device further comprises a support disk.

[0018] In a further advantageous variant, it is provided that a check valve is provided on at least one of the connecting elements, preferably on both connecting elements.

[0019] It is further advantageous if the respective connection element is designed as a cutting ring screw connection, flare screw connection, threaded connection, clamp screw connection or plug connection.

[0020] According to the invention, a measuring device comprising a measuring device and a measuring coupling according to the above disclosure is further proposed, in which the measuring device is connected and / or connectable to the measuring connection. Furthermore, the measuring device is a pressure measuring device and / or a temperature measuring device.

[0021] The features disclosed above can be combined as desired, as long as this is technically possible and they do not contradict each other.
