Gravimetric measuring system
A gravimetric measuring system ( 10 ) includes a balance ( 12 ) with a weighing chamber ( 22 ), surrounded by a plurality of weighing chamber walls ( 23, 24, 26, 28 ); an electromechanical weighing system ( 181 ); and an electronic control apparatus ( 36 ) controlling the system operation according to routines stored in a memory ( 363 ) thereof; and a plurality of functional modules ( 14, 16 ), configured to be inserted into module receptacles, arranged on at least one weighing chamber wall ( 28 ). The at least one weighing chamber wall ( 28 ) is designed as a carrier structure, with recesses ( 283 ) which constitute clearances occupying a majority of the wall surface and which form the module receptacles. Either the functional modules ( 14, 16 ) or diaphragms ( 15 ) without a weighing function close the recesses and are spatially adapted to the recesses.
1. A gravimetric measuring system, comprising:
a balance with a weighing chamber surrounded by a plurality of weighing chamber walls;
an electromechanical weighing system; and
an electronic control apparatus for controlling the system operation according to routines stored in a memory of the electronic control apparatus;
wherein one of the weighing chamber walls is a rear wall comprising a ribbed or lattice structure configured as a carrier structure having a wall surface defining recesses constituting clearances which are open towards the weighing chamber and configured as module receptacles;
a plurality of functional modules configured respectively for insertion into the module receptacles; and
a plurality of diaphragms, which have no weighing function, and which are spatially adapted to the recesses;
wherein the recesses are configured to be closed by the diaphragms or the functional modules;
wherein the recesses occupy a majority portion of the wall surface of the one weighing chamber wall; and
wherein the carrier structure has in a region of one of the recesses, a device-side identification interface component, which is contacted in an identification data-transmitting manner by a corresponding module-side identification interface component, when a respective one of the functional modules is inserted into the one recess.
2. The gravimetric measuring system as claimed in claim 1 , wherein:
the device-side identification interface component is designed as an optical, magnetic tactile, radio or electronic receiving unit; and
the module-side identification interface component is designed as a corresponding optical, magnetic, tactile, radio or electronic transmitting unit.
3. The gravimetric measuring system as claimed in claim 1 ,
wherein the carrier structure has, in a region of one of the recesses, a device-side thermal interface component, which is thermally connected to a central cooling apparatus and which is thermally contacted by a corresponding module-side thermal interface component, when the respective functional module is inserted.
4. The gravimetric measuring system as claimed in claim 1 , wherein:
the weighing chamber rear wall is positioned as a separating element between the weighing chamber and a weighing system chamber, which encloses a weighing system that bears a sample carrier arranged in the weighing chamber, and
the recesses of the carrier structure are closed on the weighing system chamber side by a fixedly installed end wall.
5. The gravimetric measuring system as claimed in claim 4 , wherein the fixedly installed end wall seals the weighing system chamber and precludes accessibility of the weighting system chamber to a user of the balance.
