    摘要: A toploaded balance in accordance with the principle of the electromagnetic compensation of force with a divided upper guide rod (3, 3') and a divided lower guide rod (4, 4') which together as a parallel guide connect a load receiver (2) to a system carrier (1) fixed to the housing, which system carrier (1), load receiver (2) and guide rods (3, 3', 4, 4') form a one-piece base, with a translation lever (5) rotatably mounted by two flexible articulations (7) on the system carrier (1), with a coupling element (12) connected by flexible articulations on the one hand to the load receiver (2) and on the other hand to the short lever arm of the translation lever (5), with a magnet build, as viewed from above, into the free space between the parts of the guide rods (3, 3', 4, 4') and their extensions on the system-carrier side and with a coil fastened on the longer lever arm of the translation lever (5) and extending into the air gap of the magnet, the translation lever (5), the two flexible articulations (7) for mounting the translation lever (5) and the coupling element (12) with its flexible articulations (13, 14) are also a one-piece component of the base. In this manner errors by screwing the flexible articulations (7) and warping and non-reproducible return forces from other screw connections can be avoided.

    摘要: An electronic balance including a housing (1), a weighing scale (2), a windshield (3), which preferably at least partially surrounds the weighing scale, and a display and operating unit (4) which is connected to the balance housing. The connecting part (5) between the display and operating unit (4) and the housing (1) consists essentially of a material with poor heat conduction properties. At least one vertical radiation protection plate (6) is provided between the display and operating unit (4) and the housing (1), and the connecting part (5) is configured in such a way as to impair air convection on both sides of the radiation protection plate(s) (6) preferably to the least extent possible. This results in excellent thermal decoupling between the display and operating unit (4) and the housing (1).

    摘要: A method for testing integrity of a hydrophobic, porous diaphragm filter (42) includes arranging the filter (42) in a non-wetted state in a test housing (30) so that the filter (42) divides an upstream housing region (30a) from a downstream housing region (30b), completely filling the upstream housing region (30a) with a test liquid that does not wet the hydrophobic diaphragm filter (42), incompletely filling a reservoir (12) that is connected to a liquid feed line (16) of the test housing (30), charging the reservoir (12) with compressed air at a constant pressure below the intrusion pressure of the filter, and determining a substance flow at the reservoir (12). The substance flow to be determined is a mass flow out of the reservoir (12) determined as a decrease in the overall weight of the reservoir (12).
