Abstract of the Disclosure A method and an apparatus is disclosed for measuring weighing and/or mass of an object. The object to be measured iis subjected to an input frequency signal supplied to a piezoelectric crystal. Another piezoelectric crystal supporting the object is caused to vibrate in response to the input frequency signal and the mass and/or weight of the supported object. This second vibrating piezoelectric crystal will then produce a frequency output signal, whose amplitude is a function of the mass (and/or weight) of the object being measured. The frequency of the input and the output signals are substantially the same.
