Garner Bin-Master Rotary Automatic Level Indicator

The Seedburo Rotary Level Indicator operation is based on a low torque, slow speed synchronous motor. The motor rotates a paddle which senses the presence of material at the level of the unit. As a high level indicator, the paddle will rotate constantly until interrupted by material stalling its motion. As a low level indicator, the paddle will begin to rotate as soon as material has dropped below the desired level. This actuates a micro switch that controls an audible or visual signal (see accessories below).

Thanks lyn.

"Bindicator" is another brand name of the same idea. When the rotating paddle stalls, the motor frame rotates slightly and activates the switch.
