Level detection of tuning fork method
Level switch for powder and liquid material
No calibration required,
Failure safe modes
Principle
The tuning fork of level switch operated by using two piezoelectric elements built-in on vibration tube. The first piezoelectric element triggered by pulse signal that created from circuit to transport vibration energy out, and the other piezoelectric element receives the vibration and transmits it to output electric signal. While the probe contacts material, it will cause the frequency change of output signal and the vibration will hold and send out the relay on at the same time. Tuning fork of level switch provides reliable and maintenance-free for bulk solids. This device can withstand fiercely lateral loads and static electricity.
For friendly use, Fail-safe is equipped as standard to prevent malfunction cause by power shortage.
Feature
Application
The MVL series detects the min. and max of level in bins, silos and hoppers, filled with powdered materials.
