Gravimetric measuring system

A gravimetric measuring system, comprising:

• a balance with a weighing chamber surrounded by a weighing chamber wall;
• an electromechanical weighing system;
• an electronic control apparatus for controlling the electromechanical weighing system operation according to algorithms stored in a memory of the electronic control apparatus;
• and
• a plurality of functional modules configured for insertion into respective module receptacles arranged on the weighing chamber wall,
• wherein each of the module receptacles has a device-side identification interface component arranged therein and each of the functional modules has a corresponding module-side identification interface component arranged thereon,
• wherein the module-side identification interface component, upon insertion of each functional module into respective module receptacles, either mechanically or magnetically interacts with the respective device-side identification interface component to provide information on type and number of functional modules that are inserted into the module receptacles, and transmit the information to the control apparatus,
• wherein the control apparatus is programmed to identify each functional module, inserted into the module receptacles, through interaction between the respective device-side and module-side identification interface components and to select given ones of a plurality of operating routines according to algorithms stored in the memory,
• wherein the balance comprises a cooling apparatus programmed to be controlled by the control apparatus for cooling the weighing chamber,
• wherein the control apparatus is configured and programmed to:
• a) control the cooling apparatus with a static cooling capacity (Pst) that is dependent on a type and number of the functional modules that generate heat during operation and are identified through the interaction of the respective device-side and module-side identification interface components, and
• b) control the cooling apparatus through a closed loop control to constantly maintain a predetermined weighing chamber temperature (T), the closed loop control having control parameters which are dependent on the type and number of the identified functional modules that generate the heat during the operation, and
• wherein the static cooling capacity (Pst) in accordance with a) is derived from a sum of individual heat outputs (Pmi) of the functional modules identified by the control apparatus upon insertion of the functional modules into the module receptacles.

• an electromechanical weighing system;
• an electronic control apparatus for controlling the electromechanical weighing system operation according to algorithms stored in a memory of the electronic control apparatus;
• and
• a plurality of functional modules configured for insertion into the recesses defining the module receptacles,
• wherein each of the recesses defining the module receptacles has a device-side identification interface component arranged therein and each of the functional modules has a corresponding module-side identification interface component arranged thereon,
• wherein the control apparatus is programmed to identify each functional module, inserted into the recesses defining the module receptacles, through interaction between the respective device-side and module-side identification interface components and to select given ones of a plurality of operating routines according to algorithms stored in the memory,
• wherein the balance comprises a cooling apparatus programmed to be controlled by the control apparatus for cooling the weighing chamber, and
