What is claimed is: 1. A weighing system comprising: a plurality of weighing cells configured to respectively weigh a plurality of materials, wherein the weighing cells have substantially identical respective configurations, are arranged interchangeably in a two dimensional array, are each releasably fixed on a carrier element, and each have an electrical connector, and wherein each of the weighing cells comprises a respective load sensor that supports a respective one of the plurality of materials. 2. The weighing system as claimed in claim 1, wherein the weighing cells are arranged in an array with at least 3 ×3 elements. 3. A weighing system comprising: a plurality of weighing cells each independently configured to respectively weigh each of a plurality of materials, wherein groups comprising at least two of the weighing cells are combined into respective weighing modules and the weighing modules are releaseably fixed on a carrier element and have respective electrical connectors, and wherein the weighing modules each have substantially identical respective configurations, and are arranged interchangeably in a two dimensional array. 4. The weighing system as claimed in claim 3, wherein the weighing cells are or the weighing module is releasably fixed on the carrier element, and the weighing cells lift or the weighing module lifts upwardly from the carrier element to be removed from the array arrangement. 5. The weighing system as claimed in claim 1, wherein each weighing cell has individual load sensors and wherein the weighing cells have respective, substantially square base areas and are arranged such that the individual load sensors form a rectangular equidistant array. 6. The weighing system as claimed in claim 3, wherein the weighing module has individual load sensors, wherein the weighing module has a substantially rectangular base area, the length of one edge of the base area being approximately twice as long as the length of another edge of the base area, and wherein the weighing module is arranged such that the load sensors form a rectangular equidistant array. 7. The weighing system as claimed in claim 6, wherein a node distance (a) between the load sensors of the rectangular equidistant array is less than 3 cm. 8. The weighing system as claimed in claim 3, wherein the weighing cells are each enclosed by a housing or the weighing module is enclosed by the housing. 9. The weighing system as claimed in claim 1, wherein the weighing cells are arranged in a two-dimensional polar coordinate array. 10. The weighing system as claimed in claim 1, wherein the weighing cells have a hexagonal base area and are arranged in a honeycomb array. 11. The weighing system as claimed in claim 3, wherein the carrier element has honeycomb recesses for seating the weighing cells or weighing module, the weighing cells each have or the weighing module has a collar that is complementary to the honeycomb recesses of the carrier element, and the collar positions the weighing cells or weighing module in x, y and z directions when the weighing cells are or the weighing module is seated in the honeycomb recesses of the carrier element. 12. The weighing system as claimed in claim 3, further comprising a fixation plate arranged above the carrier element in a z direction, which corrects a tilting error of the individual weighing cells or the weighing module arranged on the carrier element with aid of fixation elements, wherein the fixation plate provides a relative, spatial alignment of individual load sensors of each of the weighing cells or of the weighing module in x and y directions. 13. The weighing system as claimed in claim 3, further comprising a wiring board arranged below and at a distance from the carrier element in a z direction, the wiring board having slots respectively assigned to each of the weighing cells or the weighing module for electrically contacting electronics that respectively correspond to the weighing cells or the weighing module with a downstream signal processing unit, whereby mechanical positioning of the weighing cells or the weighing module on the carrier element establishes the electrical contacting. 14. A weighing system, comprising: a housing; and a plurality of weighing modules, the housing comprising: a fixation plate having an array of holes formed therethrough; a carrier element having an array of holes formed therethrough; and a wiring board, wherein the fixation plate is connected to the carrier element via first connecting elements and the carrier element is connected to the wiring board via second connecting elements, wherein each of the plurality of weighing modules comprises weighing cells therein, load sensors at a first end and a connector at a second end thereof, and wherein the load sensors are releasably retained in respective holes of the fixation plate, a body portion of each weighing module is releasably retained in a respective hole of the carrier element and the connector of each weighing module is releaseably connected to a respective connection slot of the wiring board. 15. The weighing system according to claim 14, wherein each of the plurality of weighing modules further comprises fixation elements that releaseably fix the respective weighing module to the fixation plate. 16. The weighing system according to claim 14, wherein the body portion of each weighing module comprises a collar that seats and aligns the weighing module in the carrier element. 17. A weighing cell for insertion in a weighing system, comprising: means for releasably mechanically fastening to a weighing system carrier element; electrical contacts; fixation elements for aligning the weighing cell with respect to the carrier element; and at least one functional element establishing an asymmetry in an exterior surface of the weighing cell and cooperating with said fastening means to prevent the weighing cell from fastening to the weighing system in an orientation other than a single predetermined orientation. 18. The weighing cell as claimed in claim 17, further comprising electronics configured to communicate with an external signal processing unit. 19. The weighing cell as claimed in claim 17, wherein the functional element comprises at least one of a beveled edge, a pin and a bore. 20. A weighing module for insertion into a weighing system, comprising: two weighing cells supported in the module; means for releasably mechanically fastening and electrically contacting the module with a weighing system carrier element; and fixation elements for aligning the module with respect to the carrier element.
