RLI
Rotary Paddle Level Indicator

         
 

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.

One Vane Rotary Paddle
 

One Vane Insertable Rotary Paddles

The RLISP1 is designed for materials over 70 PCF (coal, stone, etc.), while the RLISP2 is designed for materials between 30 to 70 PCF (powders, light grain, seed, etc.).

 
     
     
     
     
     
 
 
         
 
Three Vane Rotary Paddle
 

Three Vane Rotary Paddles

The RLISP3 (5 inch diameter) is designed for materials between 30 to 70 PCF (grain, beans, oil seeds, etc.).  The RLISP4 (7 inch diameter) is designed for materials under 30 PCF (flour and light materials).

 
     
     
     
     
     
     
 
 
         
 
Mounting Plate
 

Mounting Plates (Top & Side)

The SMP (side mounting plate) and TMP (top mounting plate) are zinc plated steel mounts with a 1-1/4 inch NPT coupling.   Stainless steel versions are also available.

 
     
     
     
     
     
         
  Can the RLI be side or top mounted?
