Online tuning fork density meter
Fork density meter Principle:
Tuning Fork density meter adopt fork sensors (one pair fork ceramic chip), one of piezoelectric ceramic chip is 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.
Fork density meter Features:
1. Inserted type, easy to install.
2. Continuous on-line measurement
3. No moving parts, maintenance-free
4. Specific conditions do anti-corrosion design
5. Temperature compensation
6. Explosion-proof certificate(Exd II CT4)
7. Do long rod type design(max can do 2m)
8. Suitable for high pressure piping(max pressure 20Mpa)
