	Operational principle

          

          
	RK086  Insert type tuning fork density meter 
is designed according to the theory of resonance. The vibration components is 
similar to two teeth of the tuning fork, the fork body vibration because of a 
piezoelectric crystal was located in the root of tooth, vibration frequency is 
detected by a piezoelectric crystal , through shifting the phase and amplifying 
circuit, the fork body is stable in the natural resonant frequency.

          

          
	When the liquid flows through the fork body, 
vibration changes, caused the change of resonant frequency, thus through 
electronic processing unit to calculate accurate density value. The relationship 
between vibration frequency and density as:

          

          
	Insert type tuning fork density meter has 
been widely used in industrial field, it is not afraid of hanging, not afraid of 
the impact, high sensitivity. It using tuning fork "resonance" principle, 
piezoelectric element is electrically driven by vibration, only probe rod 
surrounded by material surrounded by the amplitude of vibration is sharply 
reduced, resulting in switching action.
