摘要： Measurement amplification methods and devices for detecting a monopolar input signal (UE) by integrating A/D conversion. Before being digitized, the input signal (UE) is inverted according to the so-called Chopper principle and converted into a bipolar intermediate signal (UZ). A reference voltage (Uref) used in A/D conversion undergoes polarity changes synchronized with the polarity changes of the intermediate signal (UZ). Offset and drift are eliminated by totaling an even number of individual measurements.

摘要： An analog/digital converter including an amplifier (1) wired as an integrator, a comparator (2) electrically downstream from the integrator, a time counter (6) which continually counts the pulses of a pulse generator (5), a bistable element (4), and additional circuitry. The bistable element (4) drives the input network of the amplifier (1) with at least one switch (3) in such a way that in one of its two positions (“off” condition) a current Ix proportional to the analog measured value is integrated, and in the other position (“on” condition) a constant reference current Iref with opposite polarity to the current Ix is integrated in addition to current Ix. The switching of the bistable element from the “off” condition to the “on” condition is controlled by the time counter, and the switching from the “on” condition to the “off” condition (switch-off time) is controlled by the output signal of the comparator, which is generally synchronized with the pulses of the pulse generator. The pulses of the pulse generator (5) are summed to a result during the time the bistable element is in its “on” position. The additional circuitry displaces the switch-off time of the bistable element (4) beyond the time resulting from the above synchronization by a number of pulses of the pulse generator (5) determined by an arithmetic unit (31).

摘要： A scale having an electronic weighing system to generate a weight-dependent signal and a digital signal processing unit (18). The digital signal processing unit (18) has a circuit or program parts which measure the time elapsed since connection of the voltage to the scale. To dramatically reduce the time required for the scale to reach its full accuracy after connection of the voltage supply, the digital signal processing unit (18) has computation modules (34, 35) that correct the weight-dependent signal generated by the weighing system by a correction value that depends on the time elapsed. The magnitude of this correction value, starting from an initial correction value, converges with increasing time elapsed to a constant end value that differs from the initial correction value.

摘要： A method and an apparatus for dynamically checking the weight of objects (18a-c) which are guided across a weight-sensitive zone (14) of a weighing device (12) at an adjustable conveying rate by a conveying mechanism (20a-c). At regular intervals, the weight-sensitive zone (14) supplies individual measured weight values (E1, . . . , En) from which resultant weight values are derived in a digital evaluation unit (16) by averaging. The evaluation unit (16) includes a plurality of cascaded averaging filters (24a-e) which have different filter lengths that are varied by a common scaling factor depending on the conveying rate.

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.
