Yunyi Good Performance Online Liquid Tuning Fork Density Meter
Yunyi Explosion-proof Digital Insertion Digital Sensor Tuning Fork Density Meter Price
The tuning fork density meter is an online density measuring instrument based on the vibration principle, which is widely used in real-time monitoring of liquid density. Its core component is two tuning forks (vibrating forks) arranged in parallel, and the liquid density is calculated by measuring the change in their resonant frequency.
Working Principle
Vibration principle: The tuning fork vibrates at its natural frequency under electromagnetic drive. After being immersed in liquid, the vibration frequency will change due to different liquid densities (the higher the density, the lower the frequency).
Signal processing: The sensor detects the frequency change, converts it into a density value through a built-in algorithm, and outputs a standard signal (such as 4-20mA or digital signal).
