How does an electronic weighing machine work

The operation of an electronic weighing scale can be split into two parts for understanding. The first being the sensing part and the second, the processing part. The sensing part essentially contains a collection of sensors which measure the weight and convert it into electrical form for processing. The processing part then takes this signal and displays it on the LCD for a readout. The sensors used for measurement are known as load-cells. A load cell is basically a transducer [...]
