Vibrating Rod Level Switch VLSKB131Z Delta Mobrey Vietnam

Stainless Steel Sensor – ATEX Certified

The Vibrating Rod Level Switch (VLS) is an ideal solution for reliable point level detection in bulk solid materials. Designed for use in silos, hoppers, or storage tanks, it effectively handles a wide range of material densities—from fine powders and granules to coarse, clumpy solids.

Its single-rod design minimizes the risk of material bridging or clogging, a common issue with traditional tuning fork sensors.

Operating Principle

The vibrating rod is driven into resonance by an internal electronic circuit. When the rod comes into contact with material, the vibration amplitude decreases. This change is detected, and an output signal is triggered after an adjustable time delay.
