NYDE-CR Tuning Fork Densitometer Working Principle
The sensor works on the principle of component vibration, the component part being the tuning fork part immersed in the measured liquid. The tuning fork part senses the vibrations through an intrinsic piezoelectric device fixed at the bottom end of the fork body. The vibration frequency is detected by a secondary piezoelectric device fixed at the other end of the fork, and then the signal is amplified by a circuit at the top. The density of the liquid and the frequency of vibration when the measured liquid flows are closely related, and when the density of the measured liquid changes, the frequency of vibration when the liquid flows also changes. Through the equation D=Ko+KIT+KETz, the density of the measured liquid can be calculated accurately.
D = density of the measured medium without calibration (kg/m³)
T = frequency of vibration (μs).
Ko, Ki, K2 = constants
In the density detection process, NYYC-MD plug-in densitometer can automatically compensate for the effect of temperature on the density of the measured medium (D), and the pressure has no significant effect on the density.
