Rod Type Tuning Fork Level Switch Sensor


The tuning fork switch continuously monitors the change in frequency by the piezoelectric crystal and natural frequency vibration. When subjected to material damping, the amplitude drops sharply and the frequency changes significantly. These changes are detected by the internal electronic circuit and converted into a switching signal output.
