The Vibrating Level Switch is a highly sensitive and reliable level sensing device developed for limit level control of liquids and bulk solids in industrial processes. It is designed for critical control functions such as high-level alarm, low-level alarm, overflow prevention, and dry-run protection of pumps in equipment including storage tanks, silos, bunkers, and process vessels.

These switches feature a probe or tuning fork element that vibrates at its resonant frequency. When the material comes into contact with the probe surface, the vibration frequency changes; this change is detected by the electronic circuitry and converted into a switching signal for the process control system via a digital or relay output. Thanks to this operating principle, false triggering is minimized when there is no contact with the probe surface.

Key Features and Advantages

Accurate level detection based on the direct contact principle.
Versatile use thanks to a design compatible with liquids, granules, and powdered bulk solids.
Position-independent performance, enabling flexible integration in piping, tank, and silo applications.
Reliable output signal for automation applications such as alarm, conveying, or process control.
Low maintenance requirements and long service life thanks to its design with no moving parts.

Application Areas

Chemical, petrochemical, and process industries
Food and Beverage Production
Water treatment and wastewater facilities
Ceramic, plastic, and powder/bulk material production lines
Silos, bunkers, and storage systems

Vibrating level switches are used in all applications where process safety and automation control are critical, providing accurate level monitoring and early warning.
