摘要： An apparatus for determining the position of the center of gravity of a test body with a test-body receiving plate supported on at least two weighing systems with short displacement in which device the position of the center of gravity is calculated from the particular bearing forces on the weighing systems that the connection between the test-body receiving plate (2) and the weighing systems (12, 13) takes place by means of coupling elements (22, 23) which are permanently connected by their one end to the test-body receiving plate (2), which are connected permanently by their other end to a weighing system (12, 13) and which are designed to be elastically flexible by means of at least one thin area (33, 34) defining a horizontal axis of rotation. This avoids an undefined introduction of force possibly overlaid by frictional forces and frictional moments into the weighing systems and thus increases the measuring accuracy.

摘要： In an electronic balance for loading having a balance scale (3), weighing system, display (19), control keyboard (21 to 26) and a digital processing electronic circuitry in which circuitry at least one memory is present for the weighed value shown in the display (19). A first additional key (25) is present in the control keyboard (21 to 26) upon the actuation of the key the weighed value shown in the display (19) and stored in the digital signal processing electronics is decreased and upon the first actuation of the key the weighed value displayed immediately previously is taken in addition into a first additional memory. Furthermore, a second additional key (24) is present in the control keyboard (21 to 26) upon whose actuation the weighed value displayed in the display (19) is taken into a second additional memory. By means of the decreasing key the balance operator can decreased the display from the too large actual value step-by-step to the correct theortical value. Since the overload is generally only a few numerical steps of the balance display, this is achieved with a few steps. The balance can calculate the percentage overload by storing the balance display prior to the decreasing and during the conclusion of the decreasing and subsequently bring about the same overloading in the known manner for each of the remaining components. This creates the possibility even for simple loading balances without an electronic recipe memory of compensating an inadvertent overloading of a component by means of a overloading of the other components in equal percentage.

摘要： There is disclosed an electric balance with a sensor (2), a digital signal processing unit (4), a digital display (5) and switching means (6) which suppress the leading zeros in the digital display by a control means (7) which activates and deactivates the switching means (6) for suppressing leading zeros as a function of the sign of the result of measuring. In this manner, a change of sign can be signaled more clearly. It is also possible to display more leading zeros as the magnitude of the deviation of the result of measuring from the value zero increases so that the leading zeros appear in several stages, starting from zero up to a set measuring value.

摘要： The gravimetric control of a mass flow from or into a container located on a balance using a pulsating dosing pump, the output signal of the balance is digitally filtered in such a manner that the course in time of the mass flow is cyclically estimated from the filtered wighing signal. This estimated value of the course in time of the mass flow is used to calculate the course in time of an auxiliary mass flow which compensates the pulsation of the mass flow of the pulsating dosing pump and a speed course is calculated from the course in time of the auxiliary mass flow for driving an auxiliary dosing pump.

摘要： An electronic scale having a measuring sensor (1 . . . 16), a digital signal processing unit (18), a digital display (19), a bubble level (20), which includes a container (21) that is partially filled with a liquid (22) while forming a gas bubble (23), and circuit component or program routine in the digital signal processing unit (18) for detecting a displacement of the gas bubble (23). An additional circuit component or program routine detects the diameter of the gas bubble (23). The diameter of the gas bubble changes due to vertical vibrations of the scale. The signal from the measuring sensor (1 . . . 16) falsified by vibrations can thus be corrected by the digital signal processing unit (18) by calculation, making use of the diameter signal.

摘要： A weighing scale, e.g. a top-pan scale, having a scale pan (01, 02) supported on a force transducer, and a corner load sensor (03, 04, 06, 08, 09) measuring the tilting of the scale pan (01, 02) relative to the force transducer. The corner load sensor includes a light beam source (03, 04, 06) emitting a first light beam and a second light beam. The first light beam and the second light beam are directed toward a reflecting surface on an underside of an arrangement that includes the scale pan (01, 02). The first light beam and the second light beam are respectively inclined relative to the reflecting surface of the untilted scale pan (01). The corner load sensor (03, 04, 06, 08, 09) of the scale also includes a first optical sensor (08) measuring the first light beam reflected by the reflecting surface. If no corner load exists, a predetermined proportion (12) of the reflected first light beam is directed to the first optical sensor (08). If the scale pan (02) is tilted, the proportions of the reflected light beams which fall on the two optical sensors (08, 09) change. The corner load sensor (03, 04, 06, 08, 09) has an evaluating unit determining the tilt of the scale pan (01, 02) dependent on the light quantities measured with the two optical sensors (08, 09).

摘要： A weighing device having a plurality of digital weighing cells (164), each including a sensor connected to a force transmission unit (163), each generating a digital measurement value corresponding to a transmitted force at a measurement time point, and including a data processing device that converts the digital measurement values to transmission units configured to be transmitted over a data communications line (20) to a central control unit (18) connected to all weighing cells for analysis of the transmission units. The central control unit (18) calculates a digital combination value based on the transmission units originating from the various weighing cells (164), the combination value representing a weight force with which the weighing device (16) is loaded at a weighing time point. The conversion of the measurement values to transmission units involves a pairing of each converted measurement value with a time value.
