Actively Protecting your Inventory

The Roto-Bin-Dicator PRO model is a genuine fail-safe level switch, performing self-diagnostics while in and out of material to protect your dry bulk investments.

Detect Faults in and out of Material

As a genuine fail-safe sensor, Roto-Bin-Dicator PRO can perform complete self-diagnostics in and out of material. Other paddlewheel devices can only perform diagnostics when the paddle is not in material. PRO provides undeniable confidence that the unit is functioning.
