Abstract: 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).

Abstract: An electronic weighing sensor (10) having a digital signal processing unit (19), which includes at least one filter (12) with low-pass characteristic. By means of the filter (12), the direct-current component (m) is determined from the output signal of the weighing sensor and the weighing result is derived therefrom. A signal, which is dependent on the amplitude of the vibrations, is determined by the digital signal processing unit (19) and electronic components (18) change the direct-current component (m) as a function of the magnitude of the vibration-dependent signal. This significantly improves the performance of the weighing sensor (10) with respect to shocks and vibrations in the installation site of the weighing sensor (10).

Abstract: An analytical balance that includes a balance scale, a wind guard encircling the balance scale, and an apparatus for generating an ionized stream of air for dissipating electrostatic charges of goods to be weighed. The apparatus for generating an ionized stream of air includes a blower that draws in air from the weighing space into at least one boundary surface of the weighing space. The blower also recycles the air back into the weighing space via at least one exhaust opening at another point. In this manner, highly effective dissipation of electrostatic charges is possible, and the stream of air can be conducted so that it exerts scarcely any vertical forces on the goods to be weighed. The analytical balance is very user-friendly in operation. Additionally, the apparatus for generating an ionized stream of air is preferably structured to be an easily installed optional component of the analytical balance.
