Description

Vibration module of modular measurement system and modular measurement system Technical Field The present invention relates to a vibrating module of a modular measuring system for measuring a measured variable of a fluid measured substance, in particular a modular coriolis mass flowmeter, and to a modular measuring system for measuring a measured variable of a fluid measured substance, in particular a coriolis mass flowmeter. Background From WO 2019/017891 A1 or WO 2021/121867 A2 in connection with german patent application DE 102021105397、DE 102020133614、DE 102020132685、DE 102020133851、DE 102020133566、DE 102020132986、DE 102020132686、DE 102020132685、DE 102020131452、DE 102020132223、DE 102020127356、DE 102020114519 or DE 102020112154, modular vibration measuring systems are known in each case, i.e. formed by means of a base module, a vibration module mechanically connected to the base module, together with measuring system electronics, and electrically connected to the base module, and for detecting at least one measured variable of a fluid measured substance flowing in a (measured substance) line, i.e. for determining a measured value of one or more measured variables of the measured substance, such as mass flow, volume flow, density and/or viscosity. The base module of such a (modular) vibration measuring system has a housing with at least one chamber at least partially enclosed by a housing wall, and one or more electrical coils, for example cylindrical and/or designed as air coils, which are placed (at a distance from each other) inside the chamber of the housing and are at least indirectly mechanically connected to the housing wall. Each of the coils is also electrically connected to measurement system electronics. The measurement system electronics may be at least partially housed inside the housing and/or at least partially outside the housing-e.g., housed in a separate electronics housing. In particular, the base module is also configured to receive the vibration module of the measuring system and to be mechanically fixed (forming a vibration type transducer) but still detachably connected thereto, in particular by forming the vibration measuring system itself, which is also in particular done such that the vibration module is locked in the base module or cannot be moved. The vibration module of the respective measuring system is also designed to be replaceable such that it can be inserted into the chamber from outside the housing of the base module or through an (insertion) opening of the housing provided in the housing wall, in particular also in the field, and it can be removed again from the base module in a non-destructive manner, possibly also without tools, in particular, i.e. removed from outside the housing and/or can be removed through a (slide-in) opening of the housing or removed without the base module itself having to be disposed or removed from the (process) plant. This allows, among other things, the subsequent in-situ insertion of the vibration module into an already installed base module, or the in-situ replacement of a defective or worn vibration module with a complete new vibration module that can alternatively be used only once or for only a specified period of time ("disposable"). The vibration module also has one or more, for example cylindrical, permanent magnets and is further configured to be mounted in the base module such that each of the permanent magnets is placed within the aforementioned cavity, but still spaced apart from the housing wall, in particular such that each of the permanent magnets is held in a static mounting position, which is predetermined in each case with respect to an alignment and/or a minimum distance of one of the electrical coils of the base module, and such that a respective imaginary longitudinal axis of each of the permanent magnets and an imaginary longitudinal axis of at least one of the electrical coils are aligned with each other or extend parallel to each other as an extension. In the measuring system in question, each vibration module also has at least one (measuring) tube, for example at least partly straight and/or at least partly curved, wherein the tube wall forms an outer side surface of the tube, in particular made of metal or plastic, and wherein the tube cavity is surrounded by the same tube wall, in particular two essentially identical parallel (measuring) tubes, and each of the above-mentioned permanent magnets is mounted on the outside of the tube wall, in particular at the first and second segment ends, i.e. two essentially identical parallel (measuring) tubes, and each of the above-mentioned permanent magnets is fixed to the outside of the tube wall, in particular to a central segment of the tube wall extending between the first segment end and the second segment end remote therefrom, in particular connected to the tube wall by means of a material bond. In addition, the vibration module or at least one (measuring) tube thereo
