The RLI rotary paddle switch is designed to detect high and low levels of bulk granular solids in bins, tanks, silos, and as blockage detectors in spouts. The detection of material is achieved by a rotating paddle. If material impedes the rotation of the paddle, the motor topples of its axis and triggers a contact. The power supply to the motor is cut and the contact signals that a critical level has been reached, which will cause the motor for any inlet or outlet to close down or start up. When the level of the material reaches normal levels again, the motor returns to its initial position and restarts.

The RLISP1 is designed for heavy materials over 70 lbs/ ft³ (coal, stone, etc.), while the RLISP2 is designed for medium materials between 30 to 70 lbs/ ft³ (powders, light grain, seed, etc.).
The RLISP3 (5 inch diameter) is designed for medium materials between 30 to 70 lbs/ ft³ (grain, beans, oil seeds, etc.). The RLISP4 (7 inch diameter) is designed for light materials under 30 lbs/ ft³ (flour and light materials).
The adjustable depth level kits are an ideal solution for the quick installation of roto-level indicators in variable heights. On demand, they can be delivered with the sensor pre -installed and configured.
Mild steel powder coated mounting flange with 11/4-inch NPT or 1 inch BSP, half or full coupling. Ensures a solid fixing to tanks silos and bins. Suitable for Binswitches, Rotosafes, Autoset .
Supplied complete with weather gasket. (Also available in stainless steel).
Can the RLI be side or top mounted?
Yes, it can be either top or sided mounted.
