Vibrating Rod Level Switch for Solid DMS VF(L), VR Series

Reliable Vibrating Rod Level Switch for Solid

VF (L)/ VR are universal level switches for powders and fine-grained bulk materials. The level switch consistently and robustly detects the minimum or maximum level. The vibrating rod is suited for usage in adhesive and abrasive applications, as well as bulk solids with extremely low density.
