Overview:

The tuning fork level switch vibrates through the resonance of piezoelectric crystals. When subjected to material damping, the amplitude sharply decreases and the frequency and phase undergo significant changes. These changes are detected by electronic circuits, processed, and converted into switch signals for output. The tuning fork level switch can monitor, control, and alarm the high and low positions of the material tank, and is suitable for liquids, powders, and granular solids. It is practical, simple, reliable, adaptable, and basically maintenance free. Both the tuning fork and output are in working condition, indicated by light-emitting diodes, and the status indication can be adjusted according to habits. It is equipped with three input modes (DC 24V, AC 110V, and AC 220V) and multiple output modes (DC current output type, relay contact output type, DC voltage output type). Both have high or low fault alarm modes and selectable instrument switch sensitivity.
