Resonant Mass Measurements Technology - Brochure

A mechanically resonant structure or resonator, such as a beam, suspended at one end resonates at a specific frequency. This frequency is known as the resonant frequency of the lever and is a function of its length and mass. When an additional mass is added to the beam the resonant frequency decreases by an amount that is proportional to the added mass. Therefore, accurately measuring the shift in resonant frequency yields the additional mass to very high precision.
