Density Sensors

Density Sensors

A device that uses vibration to directly detect the density of liquids.

It is to set a vibrator in the liquid, or to place the liquid inside the vibrator, and use the natural vibration frequency of the vibrator to change with the density of the liquid to detect the density. The device uses the property that the equivalent mass of the vibrator changes with the density of the liquid to drive the vibrator by external electromagnetic, detect this vibration and amplify it, and form a circuit that oscillates with the natural vibration frequency.
