Applications

What Are Vibrating Level Switches?

Vibrating level switches operate using a tuning fork or vibrating rod that oscillates at a fixed frequency. When the sensor comes into contact with process media, the vibration frequency changes, triggering a switching signal.

This simple yet highly reliable measurement principle makes vibrating level switches suitable for a wide range of applications where dependable point level detection is required.

Typical Applications

  • Overfill protection in tanks and vessels
  • Minimum or maximum level detection
  • Pump and valve control
  • Dry-run protection for pumps
  • Level monitoring in silos, hoppers, and pipelines

Suitable Media

  • Liquids (including oils, water, chemicals, and process fluids)
  • Powders and fine-grained bulk solids
  • Media with changing density or conductivity

Vibrating Level Switches Q & A

    + What types of media can WIKA vibrating level switches detect?
WIKA vibrating level switches are suitable for both liquids and bulk solids, including water, oils, chemicals, powders, and fine-grained materials. Their operation is largely independent of density, conductivity, and dielectric constant.
    + Do vibrating level switches require calibration?
No. WIKA vibrating level switches are factory-set and typically do not require calibration. This reduces setup time and ongoing maintenance costs.
    + Can these switches be used in harsh or hazardous environments?
Yes. Many WIKA models are designed for high temperatures, high pressures, and corrosive media, and are available with hazardous-area approvals for use in demanding industrial applications.
    + How do vibrating level switches compare to float or capacitive switches?
Vibrating level switches offer higher reliability in applications with turbulence, foam, coating, or changing material properties. Unlike floats, they have no mechanical movement, and unlike capacitive sensors, they are not affected by conductivity changes.
    + What is the typical response time of a vibrating level switch?
WIKA vibrating level switches respond almost immediately when media contacts or leaves the sensor, making them ideal for safety-critical functions such as overfill prevention and dry-run protection.
