Description
Overview of Vibrating Fork Level Switch
The Vibrating Fork Level Switch is an advanced, maintenance-free level sensor that uses a piezoelectric element to generate vibration. When the fork comes into contact with liquids or solids, the vibration frequency changes, and the electronic circuit converts this into an accurate ON/OFF switching signal. With no mechanical moving parts, it offers long service life, high reliability, and maintenance-free operation. It is ideal for turbulent, agitated, or bubbly liquids and is widely applied in petrochemical, food processing, light industry, and water treatment for high/low level alarms and control.
Features of Vibrating Fork Level Switch
Strong Adaptability – Detection unaffected by electrical properties, density, viscosity, turbulence, bubbles, or scaling. Performs reliably under high temperature and pressure.
No Calibration Required – Works accurately across various liquids without on-site calibration.
Maintenance-Free Design – Fully electronic detection with no moving parts ensures long service life and minimal operational costs.
High Sensitivity & Reliability – Precise ON/OFF switching signal triggered by changes in vibration frequency, even in challenging industrial environments.
Compact & Versatile – Simple installation for tanks, silos, pipelines, or vessels, suitable for both liquids and solids.
Flexible Output Options – Relay output up to AC250V/4A or DC60V/4A, and open collector NPN/PNP outputs up to 400 mA.
Wide Operating Range – Works in temperatures from -40°C to +150°C and pressures from -1 to +40 bar.
Applications of Vibrating Fork Level Switch
Petrochemical Industry – Reliable high/low level detection in storage tanks, reactors, and pipelines.
Food & Beverage Processing – Hygienic, maintenance-free level control in liquid and semi-solid materials.
Water & Wastewater Treatment – Accurate monitoring of water, sludge, and other treatment processes.
Light Industry & Manufacturing – Detection in chemical, cosmetic, and pharmaceutical production.
Industrial Processes with Turbulence or Bubbles – Ideal where traditional float switches fail due to agitation, vibration, or frothing.
