摘要： A double-integrating A/D converter in which an integrator output voltage, produced by integrating an analog signal input thereto, is reverse-integrated in accordance with a reference voltage having a polarity opposite to that of the analog signal. The time required for the reverse integration is measured in the form of a pulse count by means of a counter. A microcomputer for controlling the counter and a switch which selects the input to the integrator are provided with a software timer function so that the integrating interval of the analog input signal is set at will. The microcomputer also is capable of calculating a digital value, which corresponds to the analog signal, from a count recorded in the counter and from an overflow value indicated by an overflow signal generated by the counter. The signal converted by the A/D converter is capable of being applied to the weighing section of an electronic weigher.

A strain generating element includes plural strain generating portions. Each of strain gauges is a gauge of a temperature/sensitivity compensated type and is placed in a position on a corresponding strain generating portion. A bridge circuit includes the strain gauges. A zero compensation element compensates the zero of the bridge circuit in accordance with the temperature of the strain generating element, to roughly correct an output of the bridge circuit. A thermal sensitive resistor is a temperature sensor for detecting the temperature of the strain generating element. The zero compensation element and the thermal sensitive resistor are provided on a thick portion interposed between adjacent strain generating portions. A signal processor minutely corrects a roughly-corrected output of the bridge circuit. Thus, software compensation of zero can be further provided to an output of the bridge circuit, to which circuital compensation of zero is provided.

摘要： A weighing machine, such as a combinational weighing machine, has scale cells and a plurality of dummy cells installed on the same floor. The scale cells output weight signals corresponding to the weights of objects being loaded. The mode of vibrations of the floor is detected from dummy signals from the dummy cells, vertical displacements of the floor at the positions of the scale cells are calculated, and their effects are eliminated from the weight signals. Those of the scale cells not selected after a cycle of combinational calculations can be used as dummy cells in the next cycle. A memory device may be provided to store preferred combinations of such scale cells not selected that may be used for this purpose. Effects of the floor vibrations can be eliminated more accurately if the differences in sensitivity among the cells due to physical characteristics of the individual cells and/or due to the different loads on them can be taken into account either by a feedback calculation or by a formula.
