Modular metrological device, in particular for a multi-track weighing machine

A modular metrological device for a weighing machine, the modular metrological device including:

• (a) a basic base module having a sealed dustproof and watertight basic base module housing;
• (b) a plurality of extension modules, each extension module including a respective add-on base module and a respective connection module which is mechanically and electrically connected by a respective disconnectable mechanical and electrical connection to the respective add-on base module, each respective add-on base module having a sealed dustproof and watertight add-on base housing and each respective connection module having a sealed dustproof and watertight connection module housing;
• (c) wherein the extension modules are arranged adjacent to one another to form a stack of extension modules with the respective add-on base module of each extension module being mechanically and electrically connected by a respective disconnectable mechanical and electrical connection to the respective add-on base module of at least one adjacent extension module in the stack of extension modules;
• (d) wherein the basic base module is mechanically and electrically connected by a respective disconnectable mechanical and electrical connection to the add-on base module of a first extension module, the first extension module comprising the extension module located at a first end of the stack;
• (e) wherein forming the respective disconnectable mechanical and electrical connection between the respective add-on base modules of adjacent extension modules places those adjacent extension modules in a respective add-on module operating condition and forming the disconnectable mechanical and electrical connection of the basic base module to the add-on base module of the first extension module places the basic base module in a basic base module operating condition with the first extension module;
• and
• (f) wherein each respective connection module comprises a weighing component electronic evaluation unit, a weighing component electronic control unit, or a weighing cell.
