Liquid Level Switch Description
Tuning Fork Level Switch Engineering & Technical Selection
Measurement Principle
The tuning fork level switch uses a piezoelectric resonant system. Under free vibration, the fork oscillates at a fixed frequency. When material contacts the fork, vibration amplitude and frequency change due to damping, triggering a stable switching signal.
Accuracy & Reliability
Resonance-based detection ensures consistent switching behavior
Adjustable delay time prevents false alarms during filling or discharge
Suitable for variable process conditions without recalibration
Output & Integration
Relay output compatible with standard industrial control systems
LED indicators display fork vibration and output status, simplifying commissioning
Installation Considerations
Threaded or flanged mounting options
Rod length selectable to match tank, silo, or pipeline geometry
Tuning Fork Level Switch Applications & Industry Solutions
Tratamiento de agua y aguas residuales
Used for high and low level protection in tanks, channels, and treatment units where flow and turbulence are present.
Procesado químico
Reliable point level detection in aggressive or variable media, independent of electrical properties.
Food & Bulk Material Handling
Suitable for powders and granular solids in silos and hoppers, supporting automated material control.
Oil & Gas & Energy
Applied in auxiliary systems and process vessels where stable switching and safety are critical.
OEM Equipment Integration
Commonly integrated into packaged skids, tanks, and process equipment for standardized level control.
