摘要： 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.

Also, a draft shield (12) that has such a weighing chamber base (34), and has at least one side panel (26), which can be moved between an open position and a closed position. The side cheeks of the weighing chamber base form a section of the side walls (22) of the draft shield (12).

摘要： A balance with a load changing device (14) that has a magazine table, mounted to be horizontally movable and having a plurality of vertical openings (26) arranged in groups. The balance (12) has a load cell (34) and a load receptor (42) with a carrier arrangement (44) corresponding to each of the groups of openings. The magazine table and the balance are height adjustable relative to each other. In a weighing position, a group of openings above the load receptor is penetrated by the carrier arrangement. In a changing position, the carrier arrangement is positioned lower than the openings in the magazine table. The magazine table is mounted at a fixed height relative to a base (16), and the balance is height adjustable relative to the base. The travel of the balance is upwardly limited by a stop (32), which is at a fixed height relative to the base.

摘要： A purification device for water has a housing with a longitudinal axis, an upper and a lower end and a substantially round cross section. The device includes a first receptacle, arranged parallel to the longitudinal axis of the housing, for a first purification medium, and a second receptacle, which is also arranged parallel to the longitudinal axis of the housing, for a second purification medium. The receptacle for the second purification medium is arranged eccentrically with respect to the longitudinal axis of the housing.

摘要： A scale with a weighing system (14), a weighing chamber (16) that is delimited by a windshield (18), and a drive for opening and closing the windshield (18). The scale has a load transferring part (32, 34) with which the weight of the load is transferred onto the weighing system (14). A decoupling mechanism is mechanically connected to the drive for rotating the windshield (18) such that the weighing system (14) is mechanically decoupled from the load transferring part in the load direction if the windshield (18) is open in order to not introduce transverse forces into the weighing system (14) during loading of the weight.

摘要： A method for functionally testing a measuring instrument (10) for gravimetrically determining the moisture content of a material. The method includes positioning a sample to be measured (50) on a load receiver (40), heating the sample according to a predefined monotonic heating profile, determining a weight profile of the sample by measuring at least two weight values at different times, at least one of which is measured during the heating, extracting a test value from the determined weight profile, and comparing the test value with a stored reference value. The weight profile is determined by measuring a plurality of weight values at different times during the heating, and the magnitude of the gradient of a straight line segment, which is representative of a characteristic test region (160) of the weight profile, is determined as the test value. The reference value is an expected gradient value for the sample.

摘要： A method for producing a force-measuring element (10) having at least one articulation point (20) which separates one region of the force-measuring element (10) into two connected subregions (11, 12) which can be deflected in relation to one another. The method includes: providing a force-measuring element blank (10), removing material from the force-measuring element blank (10) in order to produce the articulation point (20), checking whether the deflection behavior of the subregions (11, 12) which is produced by the articulation point corresponds to a predefined specification, defining a correction form (30) which can be produced through material removal and compensates for an ascertained deviation from the predefined specification, correcting the articulation point geometry using a laser and the previously defined correction form (30), through material removal at the articulation point.
