摘要： 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).

摘要： Protruding part of a mechanism body is connected to a base frame by screws, and other protruding part is connected to an auxiliary connecting metal fittings by the screws. A machining necessary for connecting is conducted on the protruding portions, the widths of which are wide. Therefore, a sufficiently long distance can be obtained by the protruding portions. As a result, the Roberval's parts 4, 5 are not affected by stress strain, which is caused in the process of connecting, even if a size of an electronic balance in a longitudinal direction is not extended. Accordingly, it is possible to realize the compact electronic balance of high performance in which an accurate measurement can be made even if a load is given to a balance pan being biased.
