Apparatus using resonance of a cavity to determine mass of a load

Apparatus using resonance of a cavity to determine mass of a load

A scale is provided, the scale including a cavity having a resonant frequency which is alterable with variations in mass of a load applied to the cavity. The scale also typically includes a comparator operatively coupled with the cavity to detect actual resonant frequency under the load, to compare...

description A scale is provided, the scale including a cavity having a resonant frequency which is alterable with variations in mass of a load applied to the cavity. The scale also typically includes a comparator operatively coupled with the cavity to detect actual resonant frequency under the load, to compare such actual resonant frequency with a reference resonant frequency, and to produce a difference signal indicative of mass of the load.
