Description

Tuning Fork density meter adopt fork sensors (one pair fork ceramic chip), one of piezoelectric ceramic chipis responsible for generating vibrations, another is responsible for collecting vibration. Fork in different density solution with different resonant frequencies, the resonance frequencies was different, according to the relationship of different vibration and density to calculate the density. The resonance frequency of the tuning fork is between 1600-2400. The higher the frequency the smaller density.
