Abstract

Claims (30)

1. Gravimetric measuring device, comprising:

a weighing chamber with a vertical weighing chamber wall, which is formed as a support structure with cover modules detachably fixed to the support structure on a weighing chamber side of the support structure,

wherein each of the cover modules comprises, on a weighing chamber side of the cover modules, a module front wall covering the support structure at least partially,

wherein the cover modules have locking cantilevers directed towards the support structure,

wherein the locking cantilevers have vertically directed through-openings which are aligned with corresponding through-openings of the support structure as mutually aligned through-openings, and

wherein the cover modules lock to the support structure with locking rods which pass through the mutually aligned through-openings of the cover modules and the support structure.

2. Gravimetric measuring device according to claim 1 ,

wherein the locking rods positively pass through the mutually aligned through-openings.

3. Gravimetric measuring device according to claim 1 ,

wherein the cover modules each have pre-fixation cantilevers directed towards the support structure, the pre-fixation cantilevers having module-side latching elements which reversibly latch with corresponding latching elements of the support structure.

4. Gravimetric measuring device according to claim 3 ,

wherein, in each case, two pairs of the latching elements latched to one another form an articulation of the respective cover module on the support structure, which articulation is configured to pivot about a horizontal pivot axis parallel to the wall.

5. Gravimetric measuring device according to claim 3 ,

wherein the latching elements on the support structure side are configured as laterally displaceable, spring-biased ball elements, and the latching elements on the module side are configured as corresponding articulate pans.

6. Gravimetric measuring device according to claim 1 ,

wherein the cover modules each have module edge walls that extend from the respective module front walls towards the support structure and are aligned perpendicularly to the respective module front wall.

7. Gravimetric measuring device according to claim 6 ,

wherein the module edge walls comprise a lower module wall on a bottom side and an upper module wall arranged opposite to the bottom side, and the locking cantilevers are formed as tabs arranged at free edges of the upper and the lower module walls.

8. Gravimetric measuring device according to claim 6 ,

wherein the module edge walls comprise two vertically aligned module side walls, and the pre-fixation cantilevers are formed as tabs arranged at free edges of the module side walls.

9. Gravimetric measuring device according to claim 1 ,

wherein the module front walls together form a covering surface covering an entirety of the support structure.

10. Gravimetric measuring device according to claim 1 ,

wherein the module front walls together form a flat covering surface.

11. Gravimetric measuring device according to claim 1 ,

wherein at least one of the cover modules covers an empty space of the support structure, in which a primary electronic unit is arranged and fixed to the support structure.

12. Gravimetric measuring device according to claim 11 ,

wherein the module front wall of the cover module covering the primary electronic unit carries a secondary unit connected thereto.

13. Gravimetric measuring device according to claim 1 ,

wherein the module front wall of at least one of the cover modules carries a functional unit projecting into the weighing chamber.
