Vibrating Rod Level Switch for Liquids – VLS Switch

Stainless steel sensor, ATEX approved

The Vibrating Rod Level Switch (VLS) is the perfect solution for single point level switching in free flowing solids.  For tanks, silos or hopper bins, and for a wide density range of solids from fine powders, grains to agregates. A single rod design provides the solution to tuning forks which may become blocked or bridged.

The vibrating rod is energized and kept in resonance by an electronic circuit. When covered by material, the damping of the vibration is detected by the electronics which switch the output relay after a configurable time delay. The vibrating rod level switch is the perfect solution for single point level switching in free flowing solids across a wide density range, from fine powders to grains. A single rod design provides the solution to tuning forks which may become blocked or bridged.
