    • A load cell weighing apparatus comprising a load cell for generating an output voltage corresponding to load weight, an amplifier section for amplifying the output voltage of the load cell, an analog/digital converter for periodically converting the output voltage of the amplifier section to digital data, a processing unit for converting the digital data to weight data based on the amplification factor of the amplifier section and producing display data representing the weight data on a scale of a corresponding weighing range, and a display for displaying the display data supplied from the processing unit. In the load cell weighing apparatus, the amplifier section includes first and second amplifiers connected in tandem, and the processing unit includes a processing circuit for electrically reducing the number of stages of the amplifiers when the digital data input from the analog/digital converter exceeds a predetermined value corresponding to the weight at which the weighing range is switched from a light weight range to a heavy weight range.
