Abstract
This invention is an electronic weighing device, which avoids the use of costly, complex, cumbersome, and difficult to find components. In one scale (10) the displacement of a plate (11) is proportional to the mass (12) of what is set on it and controls the selective lighting on a sensitive window (24) of a device (23) like a CCD. A microprocessor (425), using a plate interface (410) controls the CCD device (23) and detects the signals. A precise measurement of the displacement of the plate (11) and so also the mass (12) is extracted by the microprocessor (425) through the electronic processing of the sequence of signals generated by the CCD Device (23) and is the shown on the scale's (10) screen (440). The invention is used in the transducer of the counterweight scale.<IMAGE>
